Article: Unreal Engine's Gameplay Ability System

While researching how to build an architecture for skills, spells, effects, etc. in videogames I found out that Unreal Engine altready had such a system. I then decided to look into it as my school's summer assignment.

The resulting 7-page article is part documentation synthesis (from several sources) and part reflection on how to cooperate between programmers and designers on using such a system.
