Figures
Each figure costs 500 Exchange Points to buy, once you've completed the requirements to unlock them in the Bonus Features section of the game. You have to find a number of BSAA Emblems and complete the indicated chapter on any difficulty, to unlock most of the figures.

Infinite Ammo
You can unlock infinite ammo for almost all the weapons in Resident Evil 5. Most of them require you to fully upgrade the weapon in question and then purchase the infinite ammo from the Bonus Features section, but some have additional requirements.
