Ghost Grenade (EU2012)
This grenade contains elerium-infused particles that, when diffused into our soldiers, causes them to become invisible. These particles will lose their elerium charge after a brief time, and competing energy sources - such as weapons fire - will disrupt them.

- Gives friendly units on its area of effect the ability to become invisible for a turn.
- A cheap alternative to Mimetic Skin or Ghost Armor. However, after you've developed and deployed either one of those improvements, you may want to bring another item instead.
