The Plasma Burster does more or less what you'd expect from the name. It releases 4 bursts of scorching plasma in rapid succession upon being thrown. Keep away from beards at all costs.

About
The Plasma Burster is the Engineer's first unlockable grenade. Once thrown, it will on-impact detonate and release four plasma bursts in the direction it was thrown. Each burst will consecutively detonate with tiny distances between each eruption. If the bursts are pointed at a wall they will be redirected to the opposite angle.
This grenade can be unlocked upon reaching Level 5 with the Engineer after which it can be purchased via the Equipment Terminal for 1200 Credits and 10 Jadiz.
