Prince of Persia 1 Level Editors
Below you will find the 5 Prince of Persia 1 level editors. If you are new to editing, I suggest you try and start off making new levels using RoomShaker. A very easy to use tool. If you have made your own levels or mod, submit it on the Prince of Persia Mods Forum.
1. RoomShaker
Popular tool for making new levels, RoomShaker, made by Brendon James, which allows people who are not expert in programming to build new levels in a very easy way (everything is reduced to a kind of puzzle building, you don’t have to know any particular knowledge to use it).
