4 (Exo Survival)
- "Grenade that detonates on contact with any surface."
- — Exo Survival description
The Contact grenade mode can be used within the Variable Grenade, available from "Atlas" onwards. After being thrown, it explodes when hitting a surface, similarly to the Mortar Round from previous games and the XM31 Grenade from the campaign of Call of Duty: Black Ops II.
The Contact Grenade is available as an individual grenade in Exo Survival mode. It can be purchased from the armory, and it is shot with the Exo Launcher. It is also the default Exo Launcher for the Demolition class.
The Contact Grenade appears in Exo Zombies.
They are generally very effective, due to the instant explosion, ability to cancel throwing the grenade, and the ability to purchase more grenades off the wall in the middle of the round (unlike the Fragmentation Grenades).
