First of all, I did not expect to play the same game as the first, even with some improvements to the battle.
To say in two words: the same.
- The same as the first (music, medals, weapons), with a good design on the characters, story and decent leveling system.
- The same as the first (movements, and too easy gameplay), and unbalanced damage combo in weapons.
Ok, it is a pretty simple game, but if you want to make a pretty decent game, or maybe "the best game ever", you should look for these things: it needs much more improvements than just the leveling system and customizations (although is not worth that much customizations, without giving any tribute to the character). Again needs more diversity of skills, such as bombs, tanks, special attacks, etc. You must work more on boosters defense and skills, such as placing a considerable significance that are not as useless and just a waste of time. Blood would also be a cool idea for the animation.
In overall, without upgrades, without defense value and without much skills, it gets kinda repetitive, but still a good game with good graphics. 6/10, 3/5.
