Arms Race is a Gene Tonic in BioShock 2 which increases the amount of ammunition found when looting containers and bodies.

Arms Race

Minerva's DenEdit

Can be purchased for 60 ADAM in Gatherer's Gardens in levels from Operations onward.


  • Arms Race is particularly useful for Little Sister's ADAM corpse gathering, as a great number of Splicers (amount increasing progressively throughout levels) will be constantly attacking you. This minimizes the need of visiting vending machines to stock up after a fight, and will give the player an advantage if an impending Big Sister fight arises.

Behind the ScenesEdit

  • The Arms Race tonic exists in The Protector Trials, but it is completely useless, as there are no lootable containers and bodies are un-lootable.
