Start game, go to the console (hit tilde ~) and type "REMOTEADMIN 1" (without the quotes) . Then type "LOGIN snipers" (also without the quotes, or try "LOGIN developer" if that doesn't work for you) and you'll be able to use the following codes.
fly 0/1 - Fly Mode
god 0/1 - God Mode
noclip 0/1 - No Clipping

loadscenario("umc_spscenario1","Level") - Load level, where "level" is one of the levels listed below.
Level List: bootcamp, cube, vertigo, brooklynsp, illegal, station, warehousesp, tucson, border, mansion, house, haunted, temple, gothic, space, plant, deadend
NOTE 1: Level loading must be done in the following way or the level will not be playable.
1) Start a new single-player game.
2) After the Bootcamp level loads, do not click the "Next" button.
3) Call up the console and enter the above LOGIN and LOADSCENARIO cheats.
4) When the loading is finished, the console will disappear.
5) Click the "next" button and the level will start.
NOTE 2: Another way to start at any level is to edit the file UMCGAME.LGS in the GORERULES folder under the game install folder. Be sure to backup this file first. Simply delete all of the mission desciptions before the one at which you wish to start and save the file. Each description will look similar to this.
mission1:
spawnCode("UMC_Mission0")
displayPage("umc_m1")
loadScenario("UMC_SPScenario1","bootcamp")
displayPage("next")
pause()
selectPlayer("player")
playScenario()
displayPage("mission_complete")
hidePage("mission_bootcamp01")
pause(4)
debugPause()
There is no need to renumber the remaining mission descriptions. Now run the game and start a new single-player game. The game will load the first mission description it finds in the edited file.
