<Half-Life 2> Collaborate is an upcoming Half-Life 2 MP teamplay modification with NPCs. There are 2 teams, Team Combine and Team Humans, with players divided in squads. Every squad leader is able to spawn & control NPCs, ammo crates, traps and more. Both teams will need to complete objectives to win the game. Work together, side by side, with NPCs & players to complete your objectives before your opponents do.

Are the Humans fighting to infiltrate a Combine base or are both teams are trying to outlast the other? Fight with all you have because you’re up against real opponents.
