Won this, wasn't gifted by devs. I'm very prolific when it comes to TD games if I do say so myself, been playing them since 1999 so I would say I'm pretty well versed in the genre. I rank this in the higher tier, perhaps a 7/10. It has a nice litte map overlay that you use to navigate through the stages. You have a Robot that serves as your base but it also gets upgraded into a mean machine with various attachments so it also serves as a hero, that's a very nice blending of functions and pretty darned creative...that alone is a nice standout to seperate it from the rest but isn't the only thing differentiating the game. Another example is the card system, when you acheieve the required stage completion factors you will get cards that you t hen combine to upgrade the array of characters and towers, sometimes you'll get gems that you can use to buy card packs from the store (only thing you can purchase) save and buy the big pack for 100 instead of the smaller pack, it's worth it. Yeah, all in all pretty fun time killer.
