You only need to use each skill platform once, not each variant. The eight skills are: Pulse, Turret, Shield, Seeker Mine, Hive, Chem Launcher, Firefly and Drone. You unlock them by completing main missions, the last one being DCD Headquarters. After that you should be able to earn this achievement easily.
Updated: only base game platforms are required. The Decoy, Trap and Sticky Bomb are not necessary.
