Zombie Driver is a top-down shooter, where you drive various vehicles, that can be upgraded with guns, armor, etc. In the story mode, you get missions to complete - in the demo, almost identical. Just go to a specified place (running zombies or shooting them in the way), and then kill all zombies in the area to rescue survivors. You can pick up various bonuses on the way, such as cash for upgrades, ammo or nitro. Graphics are a bit on the weak side, as is sound. Gameplay is acceptable, but not so great for me. I recommend you try the demo before buying.

Deadlight is a zombie game platformer, with great graphics and a unique style. The platformer part is not very demanding (just regular, long jumps and a wall jump so far). There are a few puzzles, but mostly logical and simple stuff. It also has plenty of checkpoints and quick loads, which is always welcome where a single failed jump can kill you. I don't usually like platformers, but I really like it so far. I will update this as I play more.
