I completed Drakengard for PS2 a couple days ago. The game was janky and bullshit, but it also gave an equal amount of opportunities to cheese. I accidentally broke the ai for final boss (B).
I played this air battle pretty aggressively. While chasing the boss I found a position diagonally behind where I can keep it stuck flying in a big circle. I could just eat its healthbar in peace while the boss was confused and doing nothing.
So, anyone got interesting experiences in breaking enemy behavior?


Fallout new Vegas. Mother deathclaw at the quarry.
You can run up some equipment and it will just sit there letting you kill it from a distance. Total cheese but good to know if you head to the quarry early.
