Up Your Arsenal: 2,000
Going Commando: 25
The Heavy Bouncer launched an even bigger bomb than its predecessor, which exploded into bombs about the same size as the normal Bouncer shots that could whiteout the screen. It was possible to use the Heavy Bouncer to kill Chainblade (although not in Challenge Mode) with one bomb if all the bomblets were accurate enough. This also worked on the B2 Brawler. The original Bouncer returned to Up Your Arsenal, which means that the Heavy Bouncer also returns with no differences from the previous game. This weapon had a good power level of 2000, but it came at a price. It had a small ammo capacity of 12 units.
