Finished the game. It was awesome. The only thing that was a little disappointing was the under-developed character we played. I would be happier if I could choose from different guns for example, or if there was a bit more decision making involved when purchasing upgrades. Also, boss fights did get repetitive after a while and I would suggest that in the sequel, the different weapons, heads, bodies etc. that bosses have will greatly change the tactics against bosses. One thing I must point out that I really enjoyed were the dialogs. Nonetheless, this game is definitely a 5 starer.
p.s. sorry if I had grammar mistakes
