The Hedgehog Grenade is the standard Chimeran hand-held explosive.
The hedgehog grenade when thrown will hover upwards into the sky at about man's height then fire all it's needles in every direction impaling nearby enemies to the ground and walls. More effective than fragmentation grenades as it will explode in mid-air instead of on the ground. In multiplayer the hedgehog grenade will take longer to go off.
- "The Hedgehog Grenade is a Chimeran anti-personnel munition. It is thrown like an ordinary hand grenade. Upon landing it springs up and expands into a spiny cluster. At its "kill height", the Hedgehog fires spines in all directions with enough force to pin targets against nearby walls. The effect is especially deadly in confined quarters."

The Hedgehog Grenade retains the same features.
In Co-op, it is the starting grenade for the Medic.
The Hedgehog Grenade possess the similar anti-personnel functions, but also has the ability of becoming a mine trap after landing, similar to the mines from Resistance: Fall of Man, staying in the ground until it is triggered by a nearby enemy.
