Hi cryogen,
That's a
nice trick there. I will try it later on.
Yes, NecroVision is very tough to beat on some particular levels, and even I don't like to cheat sometimes. Any game including NecroVision should be playable without Cheats.
I like to use the Cheat Codes in any PC title, but only after beating the full game. But in NecroVision I was forced to cheat, because the enemies were very tough to beat on some levels and I'm NOT a very skilled player.
Cheers.
