Left 4 Dead 2 is a first-person shooter video game developed and published by Valve Corporation. The game is set during the aftermath of a zombie apocalypse and follows the story of four survivors who must escape a city overrun by zombies.
The game features four campaign modes: the main campaign, which can be played alone or with up to four players; the versus campaign, in which up to four players can compete against each other; the survival campaign, in which players must survive for as long as possible; and the scavenge campaign, in which players must collect gas cans to refuel a generator.
The main campaign is the shortest campaign in the game, and can be completed in around two hours. The versus and survival campaigns can be played for as long as the players like, and the scavenge campaign can be completed in around 20 minutes.
Left 4 Dead 2 is a fun and engaging game that can be enjoyed by players of all skill levels. If you’re looking for a quick and easy campaign to play through, the main campaign is the shortest and most straightforward option.
