While Blitz will have to do a lot of combat during his trek through the Space Cannon facility, it's how he goes about that combat that promises to be fun. A lot of the puzzles and fighting in RoboBlitz are physics based, so fights aren't always about pointing and shooting.
Using your EMP blaster in a specific spot, for instance, can cause your airborne enemies to fall into certain traps or dangers that will deal out even more damage. Or, you could use Blitz' Point-to-Point gun to create an electrified tether between two separate objects, and then come up with creative uses for your new toy.
The puzzles are pretty open-ended as well. Each one has a specific solution, but how you get there is entirely up to you. Do you raise a platform with your hover gun? Or do you weigh down the lever that raises the platform by connecting it to a heavy object using the point-to-point gun?
