Project Zomboid (early access) | Steam | £5.99 (save £4)
We only recommend Early Access titles that we've tried and tested, and Project Zomboid is one of them. This zombie survival sandbox sim has been around for yonks, but it's still a tense, compelling, atmospheric and unremittingly grim experience even in its unfinished state. I'd naturally still suggest holding off until version 1.0 if you have any doubts about early access, but £5.99 is still good value if you're feeling adventurous. Thanks to Ronin474 @ HUKD!
