File:Q2.png An even more powerful version of the famous BFG 9000 from the Doom series, the BFG 10k is the most powerful weapon in Quake 2. When fired, it releases a large green sphere of compact energy that travels forward until it hits a wall or other obstacle. As it's traveling, it will exert its excess energy in the form of green beams that lash out at any enemies near it, usually killing them quickly. When it hits something, the sphere will explode, taking out any enemy that is within range.
