The RPG has a black frame and a tubular shape. It has red stripes circling the front of it and another red stripe near the middle. It also has pair of yellow stripes, with one being in between the red stripes and the other being at the other end of the RPG. Its lock-on laser is green.
In gameplay, the RPG can only be found in certain Stages. They can be wielded by GUN Soldiers, who will use them against the player. When fired, the RPG's shots can home in on the player over a certain range.
RPGs can be dropped by defeated GUN Soldiers that wield them or released from breakable Containers. Touching one will make the playable character pick it up automatically. As a lock-on type weapon, the RPG can unleash a homing attack on enemies. The player must hold // (whether on the ground or in mid-air) and use the control stick to target and lock onto enemies, then release to fire. By comparison, this weapon's shots have a long range and high damage output. However, it can only lock onto one target at a time, making it a poor choice for a lock-on weapon. A RPG can fire a total of six shots, and once those run out, it becomes useless. However, it can be reloaded with another six shots by picking up another RPG.
- The RPG is based on the FGM-148 Javelin.
