The achievo requirement is to play an entire LEVEL with 5 GOLD PERKS equipped.
There are 5 perk slots.
You have to reach a certain XP level to unlock all 5 slots.
You then have to have each slot filled with a GOLD levelled perk.
There are 3 types of perks: Offensive, Defensive and Other. You unlock them and level them up (bronze I, silver II, gold III ) by doing certain actions in the game. Each tier’s requirements can be seen by clicking on it.
You then have to play a whole level (all chapters in a level) with a gold perk in each of the 5 slots. At the end of the level, the achievo will pop.
