First complete the game at least once to unlock the ability to collect Animus Pivots in online games. You will obtain three Pivots via in-game tutorial, after which you must find more online by placing your pivots in a triangular formation on each level to locate more; no exact locations can be given because the Pivots you collect were actually placed by another player online before you, but you can discern their general locations from the Map menu. Collect Pivots to unlock cheats which can be enabled in the Options menu under "Animus Hack."
