The Advanced Adaptive Combat System (AACS) is intended for real freaks, who’re looking for an advanced battle experience. The AACS gives the players more tactical control over combat against strategic targets (towns). In determining their Risk Tolerance players can now, through careful consideration of their chances of beating the defenders, risk nearly everything to make their Battle Rolls a success. Of course, the endeavour can fail. For the defenders will then prepare countermeasures, which again will endanger the success of the Battle Roll.
Also, for the first time in Eysenhudt, with the AACS the players risk actual battle losses – either in damaged goods or in absenteeism or even in the loss of whole units.
The AACS builds on the Adaptive Combat System (ACS) and is meant for very advanced players (or freaks), who love the battle experiences and who’re willing to accept an expanded duration of playing time and a way more extended and advanced combat system in exchange for more tactical options and better control of the battle procedure.
