TDM is extremely unbalanced at the moment, not only with the 3x damage powerup spawning at the very start, there are also not enough powerups in the game at the moment, so i came up with some more:
2x fuel regain - you regenerate fuel 2x as fast
weapon efficiency - all weapons fire 50% faster and reload 50% faster
resistance - 10% resistance for 30 seconds
electrical discharge - allows the player to let out a discharge (C) disabling all shields in a 40m radius for 5 seconds
supersonic - gives 20% speed boost for 30 seconds
Placements:
I think the idea of having 2 powerup spawns on the map like on fissure, is a really good idea.
Spectrum keep 1st placement, 2nnd placement: between beacon C and D
Catalyst keep 1st placement, 2nd placement: behind giant rock between E and B
