A new trailer for Eko Software's How to Survive lists the strategies and rules necessary for surviving on an island overrun by zombies.
Players must keep their characters' physical needs met: Eating to combat hunger, drinking water to fight thirst and getting a good night's sleep, as well as using medicinal herbs to deal with injuries. It's also important to be able to jury-rig appropriate weaponry and know how to turn a handgun into a more accurate rifle.
How to Survive hits Windows PC, Wii U, PlayStation 3 and Xbox 360 on Oct. 23.
