Hi MiniOmega! I've been doing a bit testing with the glitches you shown me but it seems (at the moment) the oob saves around 30-50secs as to finish the level you need to still complete all objectives, so thanks for showing me this ^^ Also the oob glitch seems to be all about the mortars fire debris + doorway it works in 2 doorways on the strip in Street Battle. I had a quick look on level 3 Besieged as that one also has mortar fire spots but i had no luck.

I have put up a 4.15 run of Street Battle with the oob glitch maybe can get sub 4 minutes with some tweaks.

Will be doing more testing on doorways to see if i can work out the glitch science behind both methods.

Cheers!!!
