it is an interesting concept, thought a lot difficult due to how even firing your gun drains your health, I learn that you have to go to a power station just to gain health, and so long as the stations are powered, you can just stand there and shoot,
It does get you on your feet and keep moving, but there are times when the game became unfair because you can't shoot you have to head to a power station and you still lose health due to getting hit by a big attack.
the concept is great, though the bosses are a little too hard, I only managed to beat the first boss on easy mode, the two other bosses I couldn't beat on easy mode especially the third where it feels like I'm on the highest difficulty.
still a good game to play.
