Overall a really fun defense game; the scorpion is really powerful in the early game up to around wave 35, and even then with a mid-level assistant it'll do well enough. At around wave 47, you can max out the Steyr Aug, RAGE, and your assistant which is more than enough to complete the game. The rage makes the minigun nearly obsolete combined with the quick reload time and decent clip size of the Aug once maxed. Still really fun though! Minigun is useful for wave 59 & 60; so it's not completely useless.
I wasn't expecting this to be so intense, but it was quite fun. Thanks to this game I finally realised the true meaning of LIFE, LOVE, and UNDERSTANDING. Oh, and 15 points.
