Missing their familiar grenades, BruteForce commissioned research into a Visitor equivalent and the Masher is what evolved. This self-propelled grenade will fly to any fixed target location specified by its owner and explode on impact, doing damage to all hostile targets within its blast radius. Hit the 'G' key to select this Gear and then the 'R' key to Ready it. Then point at your target and click the left mouse button to fire.
