Another weapon I made for an unofficial mod called Raising the Bar Redux for Half-Life 2 game. This weapon is based on the original concept for a missile launcher from the beta of the game. The design is changed and altered in some places. These screenshots are made in Unreal Engine, though hopefully, this gun will make it to the Source Engine in the final release
