Stun Grenades

Swap standard grenades for stun grenades that don't cause damage, but halt movement for about 5 seconds. The stunning effect is similar to the detonation of an Airdropped Stun Mine, although it affects a slightly smaller area. Vehicles and shielded units (including Helldivers wearing the SH-20 Shield Generator Pack) cannot be stunned.

While Helldivers' movements are greatly slowed by getting stunned, this can be mitigated by going prone repeatedly or utilizing the LIFT-850 Jump Pack to get clear of the area.

Unlock Requirement
The Stun Grenades unlock at rank 5.
