9. Left 4 Dead

Left 4 Dead Gameplay

An outbreak. The pathogen responsible turns the townsfolk into zombie-like psychos.

Only four of you are immune, and you’ll need to collaborate to fight the growing menace and find shelter.

Firearms, flashlights and first-aid kits are provided. Players can share medical supplies and help heal one another.

You’ll depend your team to keep your health bars up.

When playing in Campaign mode, a dead player will be able to revive themself, but will need to be reintegrated by one of their team members.

Five campaigns are available, and although there are four playable characters, the game may be played in single player mode with AI-powered teammates.

There are also a few infected beings with special powers - some of which are playable in Versus mode.

Take your pick: chicken or corn dogs?

That’s not a selfie stick.
