The cheat adds a nice function to the sump (see through walls) and another no less pleasant one. How to enable: run the cheat, do not touch anything in it, press enter until a blue sign appears. Everything! Let's turn on the game! If it doesn't run:
won't run on Vista! If you do not have Vista, then open the task manager, select the processes tab, find the explorer.exe process and end it.
Z.Y. worked for six months. ZY2 - it is optimized from a completely different game.
