Grenade Launcher

Lore & Background

The Grenade Launcher has been a fixture of XCOM's armory since XCOM: Enemy Unknown (2012). It was not present in the original 1994 XCOM: UFO Defense. In Enemy Unknown, the weapon was designed as a tactical tool. Its explosive round creates a visible splash zone, and the player must decide whether the damage-to-enemies trade-off is worth the risk of collateral damage to friendly soldiers in adjacent tiles.

The weapon sits in the Weapons research tree, meaning it is a purely human development—no alien components required. This makes it a reliable, early-to-mid-game option that does not depend on the luck of salvaging a specific alien weapon. XCOM 2 carried the concept forward, maintaining the Grenade Launcher as a standard heavy weapon while the broader game introduced more exotic explosive options. Its presence across two major titles speaks to its enduring tactical niche: a simple, dependable way to clear a room, break a formation, or put a stop to an advancing squad of aliens in a single, thunderous shot.

Reader's Guide

The Grenade Launcher is a heavy, two-handed weapon that fires a single explosive round with splash damage. Because it occupies both hands, the soldier cannot carry a secondary weapon while equipped, and their movement is reduced. Any soldier class—Ranger, Specialist, Heavy, or Sharpshooter—can wield it, though Heavies benefit most from the damage profile while losing less relative mobility. Obtained through the Weapons research tree in XCOM: Enemy Unknown and XCOM 2, it is a human-tech weapon and does not require alien salvage.

In the tech tree it sits in the mid-tier of the Weapons lab, typically available after basic rifle upgrades but before the most advanced heavy weapons. It is not an alien-tech item. Tactically, the Grenade Launcher excels at area denial. Its splash radius makes it ideal for clearing doorways, breaking up clustered alien formations, or finishing off a wounded target that is about to be swarmed.

It is less effective against a single, isolated, heavily-armored target than a dedicated heavy rifle, so it shines in multi-enemy engagements. Pair it with a squad that can follow up on the staggered survivors rather than relying on the launcher to finish the job alone.

Did You Know?

• The Grenade Launcher appeared in XCOM: Enemy Unknown (2012) and XCOM 2 (2017), but was not featured in the original 1994 XCOM: UFO Defense.
• As a heavy weapon, equipping it prevents the soldier from carrying a secondary weapon, forcing a commitment to the explosive role for that mission.
• Its splash damage can affect friendly soldiers in the blast radius, making positioning and squad spacing a critical part of using it safely.
• Contrary to some claims, equipping the Grenade Launcher does not inherently reduce soldier movement in XCOM: Enemy Unknown or XCOM 2; mobility is affected by class and equipment weight, not by this weapon alone.
