The Plasma Grenade is a large ball of fiery plasma that sticks to the first thing it hits when thrown, such as the walls, ceilings, floors, and other players.
The Plasma Grenade exists in TS2 but could only be used through the alternate fire function of the Plasma Autorifle.
It has a fairly large blast radius and can still do a lot of damage. It is also adhesive, meaning it can be stuck to any surface, including living targets.
The Plasma Grenade is different from the standard Grenade in a lot of ways. The Plasma Grenade will adhere to any person and/or surface you throw it at. The player can hold down the grenade button to charge up his/her throw and toss the grenade a fair distance. When a bot is stuck with a Plasma Grenade, it will flail about and run in a random direction, occasionally towards the player who threw it. Similar to when you light a bot on fire with a Flamethrower.
The Plasma Grenade takes considerably longer to explode and has a low blast radius, and thus is less favourable than conventional grenades.
The Plasma Grenade is used in the TimeSplitters 2 Story Mode level, Return to Planet X, Robot Factory and Space Station through the Plasma Autorifle. It is found in thd Story Mode levels Time To Split, Machine Wars, and Something to Crow About.
