Crymod member Xpilesx has released an update for his popular CryLaunch program, Crylaunch 1.2! CryLaunch is a handy utility you can use to manage your custom Crysis levels. From the program, you can install new levels, delete old ones, and start them with either Crysis itself or the Sandbox2. It is also possible to use custom start parameters.
Installation is very simple, just extract the file and run CryLaunch! You may have to manually direct CryLaunch to your Crysis executable. In this case the Crysis.exe is located in ../CrysisRootFolder/Bin32 (or Bin64 if you use a 64bit OS).
