Rainbownator

"This spectacular rifle shoots rainbows! Does less damage than average damage initially, but damage ramps up drastically on heavily beamed targets. It can also carry up to 2 alt fire charges, which recharge over time, although they cannot be used to upgrade buildings and take 30 ammo to use." In-game description

The Rainbownator is a slot 1 weapon for Sapper that can increase its damage per shot the more you hit a specific enemy with it. Unlike the electro rifle, its explosive charge cannot be used to upgrade buildings, but shoots faster and could fill up on their own, making it purely suited for offense. It overall also deals less damage to non-humanoid targets (as the damage cannot ramp up) and does not inflict shock.

The Rainbownator is a large, bulky, white and light gray colored rifle that has a glow to it that cycles through the colors of the rainbow. Its bullets, bullet holes, and explosive charges also change colors, mostly being bright colored.

Tactics

 * hold m1


 * Its damage ramp up allows you to kill any enemy within 2 seconds, regardless of health. But be sure to aim better, as the bullets these shoot are much harder to hit despite having faster bullet speed.


 * The explosive charges can be used similarly to rocket jumping where it could launch the user high up in the sky. Paired with the throwaporter, this allows you to cover a greater distance with it.


 * You could still use charges if your ammo is under 30, but doing so would use up all your remaining ammo. If you can't aim well, you could try shooting 49 bullets first, then finish with an explosion followed by a reload to follow up more shots on your enemies.


 * It is significantly harder to hit shots with it than the electro rifle, so be sure to have good aim when using this weapon. You could also attempt to ambush enemies with the cloak switch if you could.


 * Using the catalyst allows you to overcome the Rainbownator's downside of not being able to upgrade buildings.

Trivia
theorethically the rainbownator could do over 2 million damage in 1 shot if you shoot the same enemy 50 times without missing. (actually probably like 10 million idk)
