A.C.E.S.

The A.C.E.S system allocates points into 3 different categories; Marksmanship, Assault and Close Quarter Battle (CQB).

The Aces system originally capped off at level 20.

In July 2008 Ubisoft released the Fan Pack for Rainbow Six Vegas 2 which is a patch that raises the A.C.E.S. rank cap off to level 100. For leveling up in any of the 3 A.C.E.S categories after the original level 20, a player will be rewared 5000 experience points towards their Rank. Points that were accumulated to the A.C.E.S categories before the update was released will be added when the update is downloaded. Ranks will be changed accordingly.
