playing at Ymir bio lab and i just saw 2 HA go straight up a building on the east side. tried to go up it too but i cant. i know you jump/climb some walls but come on. am i missing how to climb up these buildings or what is this?
It's essentially just spamming jump while pushing against a vertical surface. You need 100+ fps to pull off the maneuver due to the way it leverages collision detection.
Which is why its a bug exploit. Abusing framerate to achieve something like this is extremely unfair vs all players who cannot pull it off and it kinda defeats the purpose of the LA in these places. Its no different than being able to move through terrain or abuse that trick which allowed an LA to run around with MAX health and armor or even recreating the bug where it looks like your character is still lying on the ground after a revival.
