Oh dear. This game isn't really good.
The storyline is quite hard to follow, especially with all the funky names and stuff.
The gamplay is very simple. Pause the game, click your actions / press the hotkeys, unpause the game, and watch. There is some lag even when you don't actively pause the game, and this gets rather irritating when you want to band-aid/heal the characters. It kinda sucks that you can't heal yourself, and you need another character to do that.
The camera is awkward and clunky, and you might have problems moving your troops/team around due to the camera positioning. Although you get to rotate the camera, it doesn't feel natural.
What is good about this game is that it is short. There are only 3 chapters (according to the Steam achievements). However, paying $19.99 for a short game isn't that worth the money. I would rather you spend it on X:Com. But that is just my opinion.
