Great game :) one problem..
The gameplay is really entertaining for the player and keeps the player occupied.
The main plot story is great to because it tells the player that the main character has a purpose to kill his enemies, not just to kill them for no reason.
All of the features including the weapons and monsters are really great considering the player has freedom among the weapons since he can choose what to pick up and when.
The sound effects are great also the backround music :)
One problem... the bosses.. as mentioned in the desc.. are really hard, even for myself, I have only went up to the 2nd boss then have needed to use cheats for the game in-order to pass him. The bosses need to be easier to kill especially the 2nd and 3rd boss. (Decrease it's health as a suggestion?)
Gameplay: 10/10
Features: 10/10
Story: 9/10
Enemies 9/10
Bosses 7/10
OVERALL SCORE 8/10 (The bosses pretty much ruined it)
My Opinion: Great game, needs work on bosses. :)
