Past Episode 4 Damage Plane in Jobless Devmap
7Don't get your hopes up - I did this using a PS2 emulator and a copy of Codebreaker. I enabled Infinite Health for all three characters and Infinite Double Jumps. This isn't possible without hacking and not possible on the PS3 version as of yet.
The blimp is there, as well as the wonky camera angle that you normally get during that chase sequence. I managed to start a mission, but I forgot I had to stay where I was to not fail the mission. I jumped off and ruined my opportunity for further testing.
I noticed that the Contessa isn't affected by the damage plane, as she "walks" right through it. The guards, however, die right when they spawn. A rule of thumb - guards don't have falling animations. If they are in a position where they would need a falling animation, they instantly die. Since Sly does the falling animation when touching the damage plane, guards die when they touch it. This also happens with Fake Floor - there is nothing solid to stand on.
