"Gran Turismo 4"

Gran Turismo 4 is a 2004 racing-video-game for the PlayStation 2, the fourth installment in the main Gran Turismo series and the sixth for the overall series. It was developed by Polyphony Digital and published by Sony Computer Entertainment and was released on December 28, 2004, in Japan and Hong Kong, February 22, 2005, in North America, and March 9, 2005, in Europe, and has since been re-issued under Sony's 'Greatest Hits' line.

Originally planned for a 2003 release, Gran Turismo 4 was delayed for over a year and a half by Polyphony Digital, and had its online mode removed. The game features over 700 cars from 80 manufacturers, from as early as the 1886 Daimler Motor Carriage, and as far into the future as concepts for 2022. The game also features 51 tracks, many of which are new or modified versions of old Gran Turismo tracks, with some notable real-world additions.

Gran Turismo 4 was well-received critically and a commercial success, becoming one of the highest-selling games of 2005, and the third best-selling game on the PlayStation 2. The Chinese, Japanese, and South Korean releases of the game were bundled with a 212-page driving guide and lessons on the physics of racing. A limited-edition, Gran Turismo 4 Online test version, was released in Japan in summer 2006. A PSP enhanced port entitled Gran Turismo Mobile was originally planned for development, but was later renamed to Gran Turismo, which was released October 1, 2009. The follow-up game, Gran Turismo 5, was released in 2010 for the PlayStation 3.

Players accumulate points by winning races in the normal first-person driving mode, called A-Spec mode. Each race event can yield up to a maximum of 200 A-Spec points. Generally, a win using a car with less of an advantage over the AI opponents is worth more points. Points can only be won once, so to win further points from a previously won event, it must be re-won using a car with less of an advantage over the AI. There are also the 34 Missions which can yield 250 points each. Despite this, A-Spec points are experience points, not money.

The new B-Spec mode puts players in the place of a racing crew chief: telling the driver how aggressively to drive, when to pass, and mandating pit stops (by monitoring tire wear and fuel level). The speed of the time in the race can be increased up to 3x, allowing for Endurance races to be completed in less time than would take in A-Spec mode. The 3x feature, however, must be turned on after every pit stop because it resets to normal time. The game manual says that the player may speed up B-Spec mode by up to 5x, but this is believed to be a typo. B-Spec points are given out for each race completed in B-Spec mode. This increases the skill level of the AI driver in the categories of vehicle skill, course skill, and battle skill. Players can thereby use B-Spec mode in harder races as the game progresses, but this mode cannot be used on wet, dirt, and snow courses.

Another new addition to the game is the Driving Missions, which are similar in experience to the license tests, but award successful completion with 250 A-Spec points and 1000 or more credits. Each mission takes place with a given car on a given track or section of track, and a given set of opponents. There are 4 sets of missions: The Pass, in which the driver must overtake an opponent within a certain distance; 3 Lap Battle, in which the driver must pass 5 opponents over the course of 3 laps; Slipstream Battle, in which the driver must overtake identical opponents by way of drafting; and 1 Lap Magic, in which the driver starts with a significant time penalty against much slower opponents and must overtake them all in the space of a single lap. Completing each set of missions earns the player a prize car. There are a total of 5 prize cars available to be won, they are the DMC DeLorean, Jay Leno Tank Car, Pagani Zonda Race Car, Toyota 7, and the Nissan R89C.

A new Photo Mode is included in the game, which allows the player to control a virtual camera, taking pictures of their cars on the track or at specific locations, including the Grand Canyon. This game is able to produce a selection of screenshots with variable compression rate (Normal/Fine/SuperFine) and size (up to 1280x960 72dpi), and the user can choose to save or print to a supported USB device.

Compared with Gran Turismo 3: A-Spec, graphics are greatly improved with more detail on cars and tracks (despite running on the same PlayStation 2 hardware). The physics are also greatly improved, with the major upgrade that cars now experience body movement, such as pitching (forwards and backward rolling) under braking. Barriers have considerably more friction to slow down the cars in GT4 (in an attempt to stop the use of "wall riding"), but there is minimal friction between cars, so the advantage obtained by running into the side of another car (instead of braking) is still present. Each of the Driving Missions and Special Conditions events give a 5-second penalty for hitting the walls or opponents' cars in this way, where the car's speed is restricted to 50 km/h (31 mph) until the timer disappears when it reaches zero.

The game features a futuristic concept car called the Nike One 2022, designed in collaboration with Nike.

"Hexen: Beyond Heretic"

Hexen: Beyond Heretic is a fantasy first-person shooter video game developed by Raven Software and published by id Software through GT Interactive Software on October 30, 1995. It is the sequel to 1994's Heretic, and the second game in Raven Software's "Serpent Riders" trilogy, which culminated with Hexen II. The title comes from the German noun Hexen, which means "witches", and/or the verb hexen, which means "to cast a spell". Game producer John Romero stated that a third, unreleased game in this series was to be called Hecatomb.

Hexen: Beyond Heretic met with highly positive reviews upon release, though the various 1997 console ports were negatively received because of problems with frame rate and controls and the aging of the game itself. Critical plaudits for the game centered on the non-linear level design and the selection of three playable characters, each offering a distinct gameplay experience.

Following the tale of D'Sparil's defeat in Heretic, Hexen takes place in another realm, Cronos, which is besieged by the second of the three Serpent Riders, Korax. Three heroes set out to destroy Korax. The player assumes the role of one such hero. Throughout the course of his quest, he travels through elemental dungeons, a wilderness region, a mountainside seminary, a large castle, and finally a necropolis, before the final showdown with the Serpent Rider.

A new series feature introduced in Hexen is the choice of three character classes. Players may choose to play as a fighter (Baratus), a cleric (Parias), or a mage (Daedolon). Each character has unique weapons and physical characteristics, lending an additional degree of variety and replay value to the game. The Fighter relies mainly on close-quarters physical attacks with weapons both mundane and magical in nature, and is tougher and faster than the other characters. The Mage uses an assortment of long-range spells, whose reach is counterbalanced by the fact that he is the most fragile and slowest moving of the classes. The Cleric arms himself with a combination of both melee and ranged capabilities, being a middle ground of sorts between the other two classes. Additionally, certain items, such as the flechette (poison gas bomb), behave differently when collected and used by each of the classes, functioning in a manner better suiting their varying approach to combat.

Hexen introduces "hub" levels to the series, wherein the player can travel back and forth between central hub levels and connected side levels. This is done in order to solve larger-scale puzzles that require a series of items or switches to be used. The player must traverse through a hub in order to advance to the next hub.

The inventory system returns from Heretic with several new items, such as the "Disc of Repulsion", which pushes enemies away from the player, and the "Icon of the Defender", which provides invincibility to each class in a different manner.

Like Heretic, Hexen was developed on NeXTSTEP. Hexen uses a modified version of the Doom engine, which allows looking up and down, network play with up to eight players, and the choice of three character classes. It also popularized the "hub system" of level progression in the genre of first-person shooter games. Unlike previous games, which had relied purely on General MIDI for music, Hexen is also able to play tracks from a CD. The game's own CD contained a soundtrack in an audio format that was exactly the same as the MIDI soundtrack, but played through a high-quality sound module. However, the most significant improvement was the addition of wall translation, rotation, and level scripting.

"Polyobjects" are the walls that move within the game. Because the Doom engine uses the binary space partitioning system for rendering, it does not enable moving walls. Hexen's moving walls are actually one-sided lines built somewhere else on the map and rendered at the desired start spot when the level is loaded. This enables a pseudo-moving wall, but does not allow moving sectors (such as seeing the tops of moving doors). This often creates problems in sectors containing more than one node, however, explaining the relatively limited use of polyobjects.

Whereas Doom, Doom II, and Heretic rely on lines within the maps to perform simple actions, Hexen also allows these actions to be activated by Action Code Script (ACS). These scripts use a syntactic variant of C, thus allowing special sequencing of game actions. Programming features such as randomization, variables, and intermap script activation enable smooth hub gameplay and are responsible for most of the special effects within the game: on-screen messages, random sound effects, monster spawning, sidedef texture changes, versatile control of polyobjects, level initialization for deathmatch, and even complex environment changes such as earthquakes manipulating floor textures and heights.

On January 11, 1999, the source code for Hexen was released by Raven Software under a license that granted rights to non-commercial use, and was re-released under the GNU GPL-2.0-only on September 4, 2008. This allowed the game to be ported to different platforms such as Linux, AmigaOS, and OS/2 (including eComStation and ArcaOS).

Hexen is compatible with many Doom source ports; Hexen's features are also compatible with Doom WADs made for source ports regardless of what game they are being played on.

The score was composed by Kevin Schilder. In contrast to Heretic, some songs in Hexen, in addition to MIDI versions, had higher-quality versions on CD. When playing in CD-audio mode, songs absent from CD would be replaced by some existing CD tracks.

Hexen was released for the Sega Saturn, PlayStation, and Nintendo 64, all released by GT Interactive during the first half of 1997. While presenting several specific differences in their respective translations of the original PC game, all of them constitute essentially the same game with no major changes to level design, plot, or overall delivery.

The PlayStation version, developed by Probe Entertainment, has the FMV scenes and Redbook audio music from the PC CD-ROM version, but no multiplayer mode. The scripting and animation is slower, enemies have only their front sprites and lack gory deaths when attacked by strong hits or weapons, and the frame rate is slower. Although all levels are present in this version and feature their correct layouts, their architecture details are somewhat simplified and there is some loss in overall lighting quality. This port is based on a beta version of the original PC version of Hexen as many gameplay tweaks are shared, such as the simpler level design and the Fighter's weapons being weaker compared to other versions.

The Sega Saturn version, also developed by Probe, inherits most of the restrictions of the PlayStation version, such as the simplified scenery architecture and the downgraded lighting, although it does feature improvements in certain aspects. The scripting is faster, and the frame rate, while not fluid or consistent, is slightly better. The enemies still have all but their front sprites missing, but they retain their gory deaths when killed by a strong hit or weapon. This version also has hidden two-player link-up cooperative and deathmatch modes, accessible only through the unlockable cheat menu. While this port shares the FMV scenes and most of the Redbook audio music from the other CD-ROM versions, it also includes some new music tracks.

The Nintendo 64 version, developed by Software Creations, retains all of the graphical quality and scenery architecture, has a consistent frame rate, and includes high detail and smooth filtering. This version also has four-player split-screen cooperative and deathmatch modes, although they must be played in low detail mode. Due to cartridge storage limitations, the Nintendo 64 version is based on the original PC floppy version and lacks the FMV scenes and Redbook audio music introduced in the CD-ROM version, although it has new narrative introductions to the levels.

Deathkings of the Dark Citadel is an official expansion pack that was released for Hexen on September 3, 1996. It features three more hubs with a total of 20 new single player levels and six new deathmatch levels. Unlike the Shadow of the Serpent Riders expansion pack for Heretic, it had to be purchased in retail stores or by mail order. This was unusual at the time, as most non-free expansion packs also included other new or revised gameplay elements. Deathkings of the Dark Citadel, unlike Shadow of the Serpent Riders, was not packaged with the original game, meaning that both had to be purchased separately, and the expansion would not work without already having Hexen. This expansion pack also did not initially include nor enable any music. Music could be fully enabled by applying a patch specially released to address this issue (usually found online under the name "dkpatch").

Each of the hubs (The Blight, The Constable's Gate, and The Nave) features one secret level, and new puzzles based on the quest items from the original game (no new quest artifacts were added). Any type of enemy may spawn on the map.

The final level of the expansion, the Dark Citadel itself, is an arena-like level, which features teleporting waves of monsters and three bosses (Fighter, Cleric, and Mage clones).
