Project Justice2000

is a multiplayer fighting game that built on the innovative gameplay introduced by its predecessor, Power Stone. Power Stone 2 allows up to four players to choose from multiple characters and utilize items such as tables, chairs, and rocks in battle. There are four different modes available for the game 1-on-1: Much like the original Power Stone, a two-character storyline game. Arcade: A four-character storyline game, with two characters advancing each round. Original: Multiplayer mode, with free choice of characters and stages. Adventure: An unpredictable storyline game, where players can collect items, cards and money. Power Stone 2 offers five interactive 3-D stages to begin with, plus the two boss stages which players can also access in Original mode. All but the Original mode is played out like a storyline, where two battles are fought on the regular stages, followed by the Pharaoh Walker boss, then another battle, and ending with the Dr. Erode boss stage. Three extra stages may be unlocked for Original mode by meeting certain requirements in Arcade mode, as well as a desert area stage, which is essentially the Pharaoh Walker boss stage, but without the boss. Though each player has their own set of default ground and air attacks, the character can execute more powerful fusion attacks after collecting three Power Stones and transforming. Power Stone 2 does not offer an opportunity to block, although tapping on the control pad just before an enemy attacks will cause you to dodge. Most of the stages are dynamic and will change as the battle progresses. For example, the airplane stage starts out on a warplane. After a set amount of time, the plane will fall apart, forcing all the players to battle while skydiving toward the ground. Shortly after, the players will fall onto a floating platform, where the remainder of the battle will be held. This, in essence, creates three sub-stages within a single one. Each stage is also littered with item boxes, which hold a random item that a player has acquired and unlocked in Adventure mode or created in the Item Shop. They may also contain Power Stones. Items are extremely diverse. Damaging items range from guns, flamethrowers, gigantic hammers, a wide assortment of swords, to bear traps, roller blades, and even a magazine that can be thrown. Non-damaging items include food that will replenish health, shields for defense, elixirs for invisibility, adhesive sprays to slow your opponents, and wings for extra jumps. Cards that can be used to mix items can also be found in Adventure mode. Furthermore, most stages also have their own collection of unique items and fixtures that the player can use. For example, the submarine level comes with turrets, small planes to drop bombs, and icebergs to throw at opponents. Each level is also highly interactive, as players can use many of the stage elements themselves. All players can also gain extra height by jumping off a wall.

The main fighting game is best described as a polygonal Marvel vs. Capcom game, with some notable differences. Control wise, the game varies from other Capcom fighting games by only having four buttons (two punches and two kicks, which is closer to the SNK game format) rather than the standard six. A player chooses a team of two characters, and fights against another two character team. The actual fights, however, are one-on-one fights, with the partner only participating by being called in when a player has enough 'vigor' for a Team Up attack, done by pressing a punch and kick button of the same pressure. The Team Ups would be some kind of double team attack by the character and partner, or (for most female characters' Team Ups) would heal the main character or give them more vigor. After the end of a round, a player (win or lose) has a choice to fight the next round with the partner from the previous round, or to keep their main character in play. The 'vigor' meter (essentially a super meter) could go up to 9 levels, with Team Ups costing two levels and super moves from a single person all costing one level of vigor. Much like the Marvel vs. Capcom games, launchers can be done that allow air combos to be performed, with all characters having universal low and high launchers. The game also had a few defensive techniques. Tardy Counters acted much like Alpha Counters from Street Fighter Alpha, allowing a player to immediately counter-attack from a blocking position. However, the restrictions on Tardy Counters are very lax; any hard normal, special or super attack can be used to Tardy counter (Alpha counters are only limited to certain special moves for each character), and Tardy Counters do not cost any extra vigor to perform (Alpha Counters required at least a level of Super Combo gauge to do). Attack Cancels allowed a player to cancel an incoming hit simply by timing their own hit with the attack, which would cancel out both attacks (though it does not nullify the remaining hits of a multi-hit move). Also, one additional level of vigor is awarded.

Mortal Kombat 4 is 1 vs 1 fighting game, similar to the other Mortal Kombat games, but this is first game in series with 3D characters models. The player can choose from 15 different fighters at the start (and several unlockables later on). Many fighters from earlier games in the series make a comeback (like Scorpion, Sub Zero, Liu Kang, Sonya Blade, Johnny Cage etc.) while other new fighters join in, like Shinook (who is the main evil character in this game), Fujin, Jarek, and Kai. Goro returns as a boss.

Tekken 3 is the third installment in the Tekken series. It maintains the same core fighting system as its predecessors but brings many improvements, such as significantly more detailed graphics and animations, fifteen new characters added to the game's roster, more modern music and faster gameplay.

Ultimate Mortal Kombat 3 combines the best of all the Mortal Kombats into a single cartridge. 23 playable characters are immediately available, such as Reptile, Cyrax, Scorpion, Sub-Zero, Jax, Katana, Sonya, and more. There are two bosses that are unlockable, as well as additional characters and a variety of new levels, some of which are interactive. Players can go against the computer one-on-one, two-on-two, or take part in the 8-fighter tournament.

Tekken 4 marks the return of Namco's premier fighting franchise, Tekken. This version features enhanced graphics, gameplay mechanics, and fearsome fighters. Newcomers engage old favorites in interactive, multileveled arenas. The addition of walls, terrain effects, position changes, and enhanced sidestepping will force you to adjust your fighting strategy. Expanded game modes such as Training, Team Battle and the new Tekken Force provide the player with a deeper gameplay experience.

Mortal Kombat Trilogy features the same gameplay and story as Mortal Kombat 3, but adds characters and stages from the other three arcade games, including Ultimate Mortal Kombat 3. Some completely new characters were also introduced. New additions to the game included the "Aggressor" bar, a meter that fills during the course of the match and temporarily makes a player character faster and stronger. It also features the Brutality, a long combination of attacks that ends with the opponent exploding.

Mortal Kombat 3 brings new elements to the 2D fighting series: multi-level playfields, "Dial-A-Combo" attacks, a "Run" button to speed up the battles, and "Vs." codes, which unlock new powers and abilities once both players enter a code sequence in pre-match-up screens. Also included are more stage fatalities and finishing moves as each warrior attempts to go one-on-one with the Centaurian enforcer Motaro, and Shao Kahn himself.
