The settings are at the bottom of my OP. As for the setup I can't explain it much better than I already did. You rush to the hacking point, killing the one enemy en route. When the enemy respawns and enters the room, you position yourself so the pillar is between the enemy and you and continue hacking. The enemy will try to un hack the pillar while you're hacking it leading to a stalemate and endless exp.
Only person AFAIK to land exactly on 200,000/200,000 gs, WITH exactly 200 games played, with 100% completion including all DLC. 11-13-11. 200th game: Brink. Final achieve: Ark King.
