Quake II

Quake II is a first-person shooter, in which the player shoots enemies from the perspective of the main character. The gameplay is very similar to that featured in Quake, in terms of movement and controls, although the player's movement speed has been slowed down, and the player now has the ability to crouch. The game retains four of the eight weapons from Quake (the Shotgun, Super Shotgun, Grenade Launcher, and Rocket Launcher), although they have been redesigned visually and made to function in slightly different ways. The remainder of Quake's eight weapons (the Axe, Nailgun, Super Nailgun, and Thunderbolt) are not present in Quake II.

The six new weapons are the Blaster, Machine Gun, Chain Gun, Hyperblaster, Railgun, and BFG10K. The Quad Damage power up from Quake is present in Quake II, and new power-ups include the Ammo Pack, Invulnerability, Bandolier, Enviro-Suit, Rebreather, and Silencer.

Quake II takes place in a science fiction environment set against the backdrop of a war between humanity and an alien race known as the Strogg, who capture and convert organic creatures into horrific cyborgs for their war machine. In the single-player game, the player assumes the role of a Marine named Bitterman taking part in "Operation Alien Overlord", a desperate attempt to end the war by launching a counter-offensive on the alien home planet of Stroggos. Most of the other soldiers are captured or killed as soon as they approach the planned landing zone. Bitterman survives because another Marine's personal capsule collided with his upon launch, causing him to crash far short of the landing zone. Bitterman fights his way through the highly industrial Strogg city, destroying strategic objectives along the way, and finally kills the Strogg leader, the Makron, in his orbital asteroid base.

Originally, Quake II was supposed to be a new game and intellectual property; titles like "Strogg", "Lock and Load", and just "Load" were toyed with in the early days of development. But after numerous failed attempts, the team at id decided to stick with Quake II and forgo the Gothic Lovecraftian horror theme from the original in favor of a more sci-fi aesthetic.

It was a conscious decision [to change Quake II's direction] and controversial inside the company. We weren't happy with the [original] Quake story. [John] Romero was gone, so there was no one left to defend it. Kevin Cloud headed up Quake II and he wanted to make it story-driven.

Quake II received very positive reviews across all platforms. Next Generation reviewed the PC version of the game and stated that "all in all, id should be commended for the advancement of its technology and improvement in its single-player level design, but it's going to be up to mod designers to provide the necessary additions to the multiplayer game in order to make it stand out from Quake." GamePro said the game "lives up to its impossibly high hype." 0 out of 5 in all four categories (graphics, sound, control, and funfactor).

On aggregating review website GameRankings, the PC version held 87%, the Nintendo 64 version 81%, and the PlayStation version 80%. AllGame editor Michael L. House stated, "the beauty of Quake II is not in the single-player game, it's in the multi-player feature." GameSpot editor Vince Broady described Quake II as "the only first-person shooter to render the original Quake entirely obsolete."
