Boosts are pickups in Project Exonaut that can make your exosuit perform better for a short time.
There are 4 types of boosts:
Attack boost gives your shots more damage, including the heavy weapons. The Team Attack boost gives you and your teammates extra damage to you their shots.
Speed boosts increases your exosuit's moving speed. The Team Speed boosts increases you and your teammates moving speed.
Armor boosts increase your exosuits shield, meaning your exosuit can take a bit more damage. The Team Armor boosts increases you and your teammates' exosuit shields.
Stealth boost makes your exosuit invisible. Shooting while invisible will make you visible for a second, depending if the player is on Battle or Team Battle.
