The Bison B45 was a primary weapon for the Gunner class in Blitz Brigade. It is a grenade launcher with a capacity of 8 grenades in its cylinder, and is overall comparable to the Bouncy Joe and the Rancor. In-game, the B45 is very useful against mass infantry, as the grenades deal a lot of splash damage and direct hits, which also do enough damage to finish off opponents. As for the other stats, the magazine capacity is a major advantage over the Bouncy Joe and the Rancor. However, the rate of fire is somewhat slow and the critical chance is at 0%. The only real downside to the weapon is that the Bison takes a very long time to reload. Moreover, this weapon can be considered worthless when compared to the splash damage weapons of the Demolisher. Overall, if the player still has this weapon, they should be considered rather lucky, as this weapon is possibly one of the best weapons to use for the Gunner. It is based on the RG-6 Grenade Launcher.
Other facts:
- The grenades have a shorter cook time than on the Bouncy Joe and on the Rancor.
- In late 2014, this weapon was removed from the shop for unknown reasons, but disappeared completely after a tournament where the player would get a free Bison. When the tournament was over, the Bison never returned in the shop, and was no longer available. The Bison may have been removed due to people complaining about the power because it was extremely powerful back then.
