Is it still worth playing?

Valve's 2009 cooperative first person shooter and survival horror game for Windows and Xbox 360, the sequel to Left 4 Dead. Four new survivors, Coach, Ellis, Nick and Rochelle, fight through five campaigns of three to five levels each, from Savannah to New Orleans, with safe houses as checkpoints. AI Director 2.0 adjusts spawns, items, layout, lighting and weather to how the players are doing. You carry one item per equipment category, melee weapons are new, and there are new Special Infected, the Charger, Spitter and Jockey, plus Uncommon Infected unique to each campaign. Modes include Campaign, Versus, Survival, Scavenge and Realism. Special infected that each change how players have to move and fight, and finales that break up horde defense, still keep every run from repeating today.
