yeah i managed it tooo did u managed to escape legs tied (hoping) the last game? i only managed it without legs tied or with the bomb thats the easier once ::P
I did with the legs tied also, just had to be careful not running out of air. You can actually see your captor behind the glass room and adjust your timing (when to leave the stairs corridor towards the elevator room). But I only managed to unlock the catsuit in that level.
You can unlock everything incredibly easily, on the main menu just type the word ''open' and you'll have everything. Don't have to press enter, don't have to do it in a command menu or mod
