Action game with zombies? Strategy game with zombies? Not at all. This, my dear players, is one rare simulation about one scientist and his experiments during a zombie apocalypse.
Just take one experiment subject and do all the stuff you cannot do in the normal world. Use daily objects, feed the subject using several disgusting things and try various weapons. Why? Why not, but the main reason is trying to understand what’s going in the undead heads. There are many and many possibilities and a story is present too. The system may be a bit complicated but after some time of playing you will be just fine.
