Grenade helicopter

Episode Two model.

Template:Hl2 point It's a time-bomb dropped by npc_helicopters. The timer is only activated when the bomb comes in contact with the world geometry, or any props. Upon touching an NPC or most other props it will detonate immediately. The bombs are also buoyant.

Note:In the HL2 Episodes, these bombs have double velocity when launched by the gravity gun. They will also delay the timer when picked up with the gravity gun, so that they can be aimed.

In code, it is represented by theCGrenadeHelicopterclass, defined in thenpc_attackchopper.cppfile.
