The way this game is played isn't unusual but the heat seeking missiles are great. Aliens are munching on planet earth and you're high above the atmosphere. Don't just sit there and watch, kill those things (but you could capture one for science, just don't make the same mistakes they did in Aliens).
I make no apologies for being a nerd. Sometimes after all the noise of blowing people up or firing on enemies amongst innocent civilians, I like to relax with a game that triggers your ability to recognize words. No explosions, no blood, just an old-fashioned word search.
