I'd like to request that there be No Crosslink added to the leaderboards, maybe with all the standard variations (NG+, MU, Any etc.); for MU, however, 4 points must be assigned to Jump Strength, since the small space between the first 2 doors upstairs on Intex makes it impossible to complete the level, unless you have hushcracker.

The door clips that make this possible actually seem to be perfectly reliable, as I've already found jumps on Crossed Wires that allow you to bypass the door from both sides, so routes could eventually be developed.

Both Industrial Espionage and The Room would need to be skipped since they would require a hatch clip, which I don't think has been found yet. Some levels either remain the same as their standard MU counterparts (CoC and Guarded), or would simply require a rerouting (Mains and Three for All) to name a couple of levels for each.

Edit: I've uploaded a playlist of most levels that require some trick to be done without crosslink, and got rid of the awfully long proof of concept video.
