I'm a lefty so my keys are assigned differently..is that forward and jump/gatehop? This issue also occured to me in Electro and I had no problems escaping.. This scenario however the invisible (to me) walls seem impermeable! Also the buildings floor isn't as level with the ground as last time, I actually checked this forum after and realised that this is a common thing, have tried running and jumping, rolling into the wall prone..I'm assuming there's no way you can get your player reset somewhere to a new spot? I'm going to keep doing what is suggested and thanks, but I fear it's going to be a grisly fate (and just found my first gun in this building haha!)
