Arms:
Saw blade,
Punching does higher damage but has a higher cooldown (no passive if it is not on the punching arm), pressing E/Q turns on the saw and shoots the saw forward (like the custom projectile), punching is reverted to normal until the ability is off cool down
E/Q damage: 15
High knockback
Legs:
Rocket boots,
Decreases speed but greatly increases jump height
Torso:
Jetpack,
Holding jump while midair allows the user to hover for a max of 6 seconds, it uses a fuel bar that decreases as you hold it, to recover your fuel you must do damage to other players:
2% charge per long range ability
5% charge per punch
7% per close range ability
20% per kill

Head:
X-ray visor,
Out lines all players (outlines show though walls ofc) and shows their abilities over their heads (maybe it could also show their inventory)
Please give me feedback, id greatly appreciate it, I'll probably add more later but this is what I got for now
