All Zombies Must Die is a solid shooter with RPG elements and a decent level of character upgrading. Unfortunately, it's let down a little by the monotonous missions of 'kill that' or 'collect this'. Rachel isn't a particularly likable either - of course, you don't have to use her at all!
With the exception of a few controller-hurling quests, I enjoyed my time with All Zombies Must Die, but that doesn't mean I can let it pass for being such a shallow experience. Once you've taken your first quest from a gatekeeper and moved to the next area, you know what to expect for the rest of the game. That's not the worst thing in the world, but it's not the most exciting.
There is a lot to love with All Zombies Must Die, from its more humorous writing to its charming visuals, but ultimately the game fails to deliver the in-depth multiplayer experience it set out to. There's a solid experience to be had from start to finish, but unless you've been in a coma, or underneath a rock for the last few years, you've probably already played this game.
All Zombies Must Die is not a bad romp, just a mind-numbing one after a while. You know what to expect after the first 20 minutes, and it never deviates from the formula.
All Zombies Must Die takes a timeworn premise that should be fun and cathartic and seemingly goes out of its way to make it repetitive, fiddly and annoying. If you have a trio of friends close to hand, the co-op aspect might just be enough to rescue it from the depths of mediocrity, but if you're planning on playing solo you'd be far better served by trying one of the dozens of other zombie blasters on the market.
