The video above is the Alienation This Trophy Is Much Easier Than it Looks Trophy Guide and shows how to unlock This Trophy Is Much Easier Than it Looks Trophy in Alienation.
For this trophy you have to keep in mind that you don’t need legendary weapons. So, get 4 level 30 blue weapons because they have fewer sockets to fill.
Equip the weapons and socket them with level 6 cores. The trick here is to have weapons with only few slots, otherwise you will have to loot a lot. The number of sockets in your weapons determines the difficulty of this trophy.
