Zombie Attack is a fun action/defense game where you are only armed with a baseball bat and your girlfriend is throwing baseballs out of a top window for you to hit at incoming zombies. You have to hit them before they reach you or you die. This is mostly a game about timing and your ability to swing at baseballs at the right time so you can hit them out straight in order to strike the zombies with maximum force.
If you read the hints in-game, you’ll notice that they say to wait for the bounce. I tend to agree with this advice because I tried to hit the balls as they were coming down and was never that successful at doing so. So in that sense, patience helps. Also hitting one straight shot equals hitting several long shots in only a fraction of the time. It took like one straight shot to kill a zombie but 3 or 4 curved hits. Curved hits also can’t hit zombies when they get too close. To be good at this game, you have to be good at speed and coordination.
