Vegas is an IAF Technical Specialist. He is the more survivable of the Technical marines, enjoying the best melee bonus of all marines and a nice health bonus. The health bonus can sometimes mean the difference between success and failure of a mission that requires a tech marine. Furthermore, he has the better engineering bonus, allowing him or a nearby marine to set up turrets or seal/unseal doors rapidly.


Vegas has an almost savant-like talent for counting and memorization, a skill he put to use in various gambling houses where he won big at poker and blackjack tables. However, fortune is fickle, and after racking up massive debts and angering some important people, he had to get out. Vegas joined the IAF so he could earn the money to pay back his debts (or a sizeable seed fund with which to win back the rest), and to get away from people who want to crush his kneecaps.
