Stellar Blade

1,500 enemies might sound like a lot in a game that mostly has you in 1-on-1 fights, but it really isn't. In fact, we unlocked the ‘Cruel Liberator’ trophy before we'd beaten the Behemoth in Matrix 11 - so, about 50% of the way through the game.

Just kill what you see, and you'll have this in no time whatsoever. Considering you need to do a lot of side content for Nano Suits and side quests, you'll easily get this without thinking about it.
