XM25

The Heckler & Koch XM25 Counter Defilade Target Engagement System or shortened to XM25, is a bullpup grenade launcher featured in Warzone and Warzone: Iron Wolf.
==Warzone==
The XM25 appears in multiplayer only.
===Multiplayer===
The XM25 is the last grenade launcher unlocked in multiplayer. It is nearly identical to its Modern Warfare 3 counterpart.
==Warzone: Iron Wolf==
The XM25 returns in Warzone: Iron Wolf and will be useable in campaign, multiplayer and zombies.
===Campaign===
Calvin "Saint" Silex starts the mission Grieving Wolfpack with an XM25 along with a CZ 805 BREN with Dual Sight and Extended Clip. This is the only time the XM25 is useable. Earning three kills with a single round fired earns the Clusterluck achievement.
===Multiplayer===
The XM25 is unlocked at level 46 in multiplayer. It comes with a slight change with an auto-guided round. Players can laze individual targets using the zooming function while aiming and fire the grenades, which will track the target as it moves. Un-lazed targets within the sight will cause the grenade to behave like a standard grenade launcher. Lazing multiple targets in the scope will cause the grenades to go after the closest one.
In multiplayer, the XM25 is only a one-hit kill if directly impacting the target. Most of the time, an explosion will catch more enemies, but it can be survivable. It is best used at longer ranges, where the tracking ability can be put to great use. The guided rounds will travel directly to their target and will explode on cover if the target is behind. Thus, they should only be used in more open areas.
The Demolitionist killstreak is equipped with a buffed XM25 that has a larger and stronger blast from the grenades, although it does significantly harm the user if fired in close proximity.
