This patch when installed will eliminate chances of falling jump mechs, maintain sensor ranges when moving mechs, and eliminate headshots.
In a multiplayer game if used, it will only work as host, and transfer to all other players in the game. If your not the host, the host's normal files will be used for all players.
This download contains a MISSION.FST file that can be installed in the mcx directory in the place of the original MISSION.FST that will allow for a different spin on the game.
If you wish to get rid of this patch after installing, just place the original MISSION.FST back into the mcx directory.
