Here is the format I got for powerups that you guys should make.
(powerup name)
(Defensive, offensive, or supportive?)
(What it does)
(How it affects each tier)
[example below]
Wrench
Supportive
Repairs vehicles to full health when collected but not when used.
Tiers 1 and 2 are put back to full health but Tier 3 heals 25% back.
Automatic Shotgun
Defensive
Shoots at any vehicles that may be attacking the shooter with a barrage of birdshot for 15 seconds
Tier 1 puts it on the hood, Tier 2 puts it on the back, Tier 3 puts it on the roof or next to the cannon.
And finally:
The Flashlight
Depends on use
For 13 seconds, high beams are blinked on and off at a rate that won’t cause seizures. Going into the light covers the screen in a heavy filter.
Works with the headlights of all tiers
In some competitive games with health mechanics, some of them will have a healthkit around each corner, sometimes next to ammo boxes.
Examples include Quake and TF2.
What I think the healthkit would do is to reward people for knowing when to stop attacking and heal up. It also may be a fun idea when a dragster is missing one of its wheels and other cars must chase it down before it gets a healthkit and returns to full health.
EMP (electro-magnetic pulse)
Offensive
Disables (Stuns) the car in front of you for 2 Seconds and damages it a little, it has low range.
No changes per tier.
Mushroom
Supportive, Defensive, and Offensive
Increases all the stats of the car and doubles its size for 20 seconds
All tiers get the size up except tier 3
Mercury/Acid
Defensive
Spills a puddle of mercury/acid to dissolve cars that are too cocky when chasing you down.
Size goes up depending on tier who deploys it
Well… if I could make a technically instant win one….
M2 Sentry Gun
Defensive
Gives the car a 50 caliber sentry gun to shoot all nearby cars until the car’s health is depleted to 0.
Has no effect on all tiers
