✓ Same family of first-person shooters: shooter, first-person shooting and survival mechanics

≠ Stands apart with horror tension, ranged combat and melee combat

Everything the first game did plus melee weapons, daylight campaigns and special infected that force the team apart rather than just damage it. The AI Director still shapes every run. It absorbed the original so completely that the community split never healed, and the campaigns lean on finale set pieces that become rote once you know the safe corners.

The AI Director is the whole design: it places hordes and items based on how well you are doing, so no two runs of a campaign play the same and tension stays authored without being scripted. Four campaigns only, which is thin, and the sequel superseded it so completely that finding populated servers now takes patience.

≠ Its own twist: third-person shooting, adventure storytelling and horror tension

A co-op horde shooter whose swarm tech is the draw: hundreds of zombies climb over each other into structures, and the class system rewards coordinating rather than scattering. Levels are short and replayable. The shooting itself is functional but unremarkable, and the campaign chapters are thin connective tissue between the set-piece swarm moments.

Wave-based co-op against slow, heavy specimens, built around a between-round shop and perks that level by playstyle rather than by menu. Weapon feedback is meaty. It shows its origins as a mod — level design is functional rather than crafted, and later waves come down to holding one corridor while a friend welds the door behind you.

Three separate campaigns — Marine, Alien and Predator — each rebuilding the game around a different body: the Marine's motion tracker and dread, the Alien's wall-crawling, the Predator's cloak and vision modes. The Marine campaign is the one that holds up. The other two are short and thin by comparison, and the multiplayer that carried it in 2010 is long dead.
