Well, I have fantasized about super weapons in a future WipEout or a Fan game.

Plasma cannon- Pretty basic. Ammo based, but instead of proton shells, it would fire mini plasma bolts. They would do considerable damage, but have a semi-slow fire rate.

Scatter bomb- If a target was available, it would lock on and fire. If there was nobody to lock on to, it would drop behind you. If locked on, it would fire like a missile and explode doing moderate damage. The explosion would also release a bunch of homing micro mines that would target all ships (besides yours) in the area. It would be capable of damaging and slowing a large crowd. If dropped, it would sit on the track like a bomb until someone approached. It would then home on the first person to pass by it, and explode in the same way as before.
