Grenades
From Mass Effect Wiki
Grenades are hand-tossed explosive charges, useful against organic and synthetic targets. The Systems Alliance uses the Mark 14 grenade, designed with retractable stabilizing fins. If the fins are extended, the grenade can be tossed like a discus, and glides long distances. With the fins retracted, the grenade can be lobbed over walls and other obstacles.
Most grenades can adhere to flat surfaces and have a 10-second fuse, allowing them to be used as makeshift shaped-charge mines or boobytraps. They can be triggered to detonate before their fuse runs out by a signal from any military hardsuit’s built-in communications gear.
The Mark 14 grenade can be modified in the field for special purposes. Common upgrades include high explosive, flashbang, and thermite paste incendiary charges. More exotic varieties include charged particle proton charges, Bose-Einstein "cryo" condensates, and cobalt-salted micro-nukes.
[edit] Gameplay
On the X-Box 360 gamepad, press BACK to throw a grenade, and then press BACK again to detonate. A grenade will automatically explode after 10 seconds. Only the player, as Commander Shepard, can use grenades.
