A game where you'll have epic moments, even if you don't have any friends to play with, you'll always find teams to play with.
If this game ever makes it to Google, it'll be worth adding the countless maps created by the community, because that's what makes it so charming...
The character voices, some of which are quite fun.
An ultra-realistic game; when you're injured, you have to find a bandage to heal your wounds or you'll die.
The suspense when there are too many zombies and you're out of ammo for your pistol, and your machete isn't enough...
And the pressure when the evacuation helicopter tells you to hurry because it's leaving... very quickly.
This game is legendary; it would be a shame to miss out on it.
