Yeah, turns out you just have to spam it really really hard

NEVERMIND I JUST SOMEHOW MANAGED TO GET LOCKED IN THE NOCLIP STATE WITHOUT SLOWMO

oh its over for this game

Found another glitch a while ago. When you jump into an on-rails state, the game disables all collision except for triggers. Spamming crouch and swap while in slowmo seems to lock that animation. After moving too far away from the jump point the game will release you from the jumping state. Doing anything else like shooting or exiting slowmo will snap you back to the rail. Even unloading the area with the rail won't prevent you from being snapped back.

This seems completely useless as the slowmo duration is dreadfully short and there doesn't seem to be many spots where you can hit a trigger through a wall to advance further :(

It only works in spots where you can shuffle left or right between coverpoints. For some reason if you quickly press shift and hold a valid direction to shuffle into, the game will shuffle you in the opposite direction, even if it is obstructed. Seems to work at 120 fps, also you need to be crouched

Found out what makes elevators work. Taking cover pushes you really close to a wall, and the game doesn't like that. When you uncover, the game will push you in the direction you're walking. If you were walking up a slope, like stairs or props, it will push you up and keep pushing until you're 'unstuck'. Toggling slowmo reduces the push-rate, which allows you to go much higher.

Here's an example vid. Normally you can't elevate up this pillar at all, but if there's a prop that you can walk up against, it will easily push you up

Unfortunately most levels where this would save lots of time don't have any collidable props :(

This works on all cutscenes and there's even various degrees in how it breaks the game

Set fps to 30, spam barrage swap and slowmo like your life depends on it and pray you get it

Oh, so you can just pass through triggers at low fps? You'd think an unreal engine game wouldn't have such issues.

Yeah, this could be used to skip almost all standoff triggers.

if you press barrage and swap weapon keys while in slowmo at 30 fps, time will stop.

You cannot do anything in this state but walk, you cannot activate cutscenes but you'll still hit checkpoint triggers. Funnily enough, this glitch can be used to skip the big hall fight where jerry closes the door behind him - the doors remain opened because the cutscene doesn't start.

Unfortunately you can still get hurt by certain triggers like lasers

another cover related glitch

To reproduce - press shift on a pillar, press shift again to stop covering, walk away a tiny bit, press shift to snap back, press shift again - you will get a tiny elevator. It elevates you much higher in slowmo.

You can clip through ceilings with it, sometimes even walls

You need to reload checkpoint after getting godmode from the shootout skip
