I had some problem Finding savegames to this game, so i past the directions here: Savegame for editing (Hex) is found here on Win7 :
Computer/Local Disk c:/Users//Appdata/LocalLow/rondomedia GmbH/Rescue2013/save
Also hope some make trainer for game, as Cheatenginee wont do it, unless ur pro at making scrits with it.
Anyhow can always use Hex editors on savegame
Hope this helped someone, Thanks
I just tryed edit Money in game with HHD Hex editor, and it worked fine.. just search current cash on savegame, when you find it, change lets say 1610 euro, to (hex) 39 39 39 39 (=9999 euro). save it, open savegame, sell something to get over 10000 ..savegame, open hex change it now to 99999 euro and so on.. this way you wont brake the savegame file.. if you need better explination, just ask.
