It's pretty awesome, I must say. It's not exactly the most challenging game ever (it's pretty hard at the beginning, but then as you get upgrades it gets pretty easy, though the last two levels are not exactly a cakewalk even when maxed out). It also has pretty simple graphics. Nevertheless I like how it fuses shooter and RPG, and I liked the storyline and how every mission underscores just how corrupt the Hegemony is. So 5/5 for me.
