I write boring, because when you have the skills maxed out, it become easy (in easy mode of course) but i love this game, and I'll try it on normal when easy mode end.
This game is too hard, ,even if you have laser + missile turrets, the very big tank rush destroy you so quickly, you can't do anything. We must can replay other area for level up. I never replay this game.
Some mo,ster are too hard to kill. The game is good but find an to overpowered monster you can't kill is not cool. IO stop playing because the game is too hard for me (this monsters are more annoying than bosses).
