Left 4 Dead 2 review

Left 4 Dead 2 is the best co-op zombie game and the best value on the list. Valve's Steam page describes a co-operative action horror FPS that takes four survivors through five campaigns from Savannah to New Orleans, with Co-op, Versus and Survival modes. The AI Director 2.0 changes the weather, routes and enemy population to match how your group is playing, which is why runs feel different each time. You get more than 20 new weapons and items, including chainsaws, axes and a frying pan, and in Versus you can play as the Special Infected. The Steam Workshop and Source SDK keep community campaigns coming. It runs on almost anything, with a 2 GB RAM minimum, and its review record is the strongest here: 97% of nearly 235,000 English reviews are positive. The trade-offs are age and focus. It came out in 2009, the story is minimal, and it is far better with three friends than with bots.
