Zombies are after you, you’re trapped in a decrepit hospital ward, and there’s no way out! Don’t panic just yet though. All you need to keep the undead out of the Gray Ward is a sturdy door – and some cleverly repurposed medical supplies.

What we love: Executing our tower defence battle plan with surgical precision. Play as one of six survivors and decide whether you’ll defend with all your might or go on the attack early. Whichever option you choose, make sure you’re playing to your strength.

Quick tip: Stumped by a level in Campaign Mode? Take your glass marble rewards to the Lab and upgrade your defence and health stats. Doctor’s orders!
