It's... good, I guess? Only complain is that it lacks abilities to deal with boss fights (like someone else pointed out). This will be absolutely stupid to add, I know, but maybe he could have a limited-ammo basic gun (basically like 10 bullets to use) that works similar to Fang's Pop-Gun but with slightly less range? In normal levels you could restore your ammo to the max by interacting with a box at the start of the level or near checkpoints. Overall, this has potential for becoming a good support class in multiplayer matches, so I guess... yeah, the 4 stars are definitely worth! [P.S: Reading back this idea, it sucks honestly]
