Okay, guys, let's not freak out about the whole Kreds thing. You get a huge portion of the game for free. Personally, I think the whole system is genius. You can't really expect people to devote so much of their time to developing these awesome games and not at least want something in return? This game is great, one of the best Tower Defense games out there. It's also a huge game with tons of upgrades and a high replay value. If you don't want the premium options don't buy them, but don't bash the game or the Kreds system.
pretty fun. simple. the twists that make it harder as your score gets higher make it more exciting and challenging. good game =) 8/10. My top score is 527,501
Great idea and done pretty well. It could use a little more content though. More cases and achievements. Also, the story mode isn't much of a story at all. Good concept and decent game but it could have been a little bit better. 7.5/10
I love this game! There's so much to do and you can play for hours upgrading your ship and then play it all over again, choosing a different upgrade path. Lot's of different types of enemies... great game! 9.5/10
incredibly fun! tons of enemies, weapons, upgrades, and achievements. good graphics, many different modes... the campaign is a little short in my opinion but aside from that I really enjoyed it. 8/10
a solid, basic action game with a good amount of unlockables and achievements, and a fair variety of enemies. The system of unlocking upgrades for your character through earning achievements works well and the simple controls are easy and come naturally. Nevertheless, it's not hugely in depth. Good for killing a few minutes. 8/10
