Across every category, Alien Blast defines itself as the very epitome of boredom. The action is dull, repetitive, and in some cases, a bit broken. The game's graphics are pretty much a sad, underdeveloped joke.
If you're anything like me, you won't be able to play it for any length of time unless you've got something on your mind that you're concentrating on that is far removed from the game. It's perfect for zoning out.
Contrary to what many hardcore gamers frequently assume, I believe there are still a lot of people who would enjoy this kind of brain-free, white-knuckle virtual leisure activity that brings back the simplicity of earlier days.
