Shield

Shield is one of the few weapons in the game that is based off on Marvel movies, the others being Gauntlet and Iron Hand. It has a solid defence, thus making it good against ranged weapons.

Blue
-Makes your shield bigger and more stable. You can't move your weapon while using this ability but it is good at blocking projectile and also does solid damage to your enemy. If you use it in mid-air, your falling speed is dramatically decreased, which makes it a good mobility ability.

Green
-This one is more of an offensive move. It lets you throw your shield at where you're aiming it. Once the weapon hit the enemy or reached a specific range limit, it will come back to you. It also collide with walls.

Red
-Makes you shoot out a vibration wave. It is both offensive and defensive since it can both damage your enemy and block projectiles (Though it can stopped when a projectile hits it).
