its a fun, flexible, and challenging tower defense game that let's you construct the paths. yes I bought the expansion packs after I beat it, but the game can be beaten using the freeware. I've been playing it FOR YEARS trying different strategies. doesn't get old and keeps you on your toes.

The game is very entertaining and difficult. It has nice little vague tie ins with Radiant, one of my favorite mobile games, and has the same type of campy humor. Anyone telling you that the game is unbeatable without the packs is honestly either really bad or weak to in app purchases. I've beaten all but the last two without packs, and then I decided to buy them to support the devs. It's a difficult game, and it's very particular about turret and module placement. Learn to play.

I liked it, but BOY does it get hard fast. I can't get past stage 3 without watching a guide, and i feel really dirty doing that. The dancing aliens are so cool too! I love that type of feature. Starting from zero and getting more decorations. Overall, better than the average tower defense game. I would recommend (don't know if i spelled that right). But don't go into it not expecting a challenge. On a side note the dialogue from doc and the commander are really funny.
