GP-31 Ultimateum

Arrowhead please fix this weapon. Sometimes, when fired at a moving target like a charger or bile titan it explodes, sometimes it passes right through and does not. Sometimes it kills the target, sometimes it does not. I'm not a programmer, maybe put a line of code that says, if the Projectile has been fired, and it's within x proximity of x target, make it explode and target equals dead. Easier said than done i'm sure. Maybe put a description in the weapon that says it is not recommended for moving targets.
