These are Outgun related tools that aren’t an integral part of Outgun. None of them is especially easy to use properly, but there are instructions and you’re welcome to try.
These tools have been made to simplify making maps. The map converter makes 0.8.5 format maps playable in other versions (0.5.0, 0.5.0-E and 1.0). The room flipper can speed up map development (especially of symmetrical maps) by flipping wall coordinates of rooms.
