Gents, A quick question I hope one of you old salts can help me with: Is there a way to "tone down" the targeting ability of the enemy AI, with either a script or perhaps by adjusting the "skill" level of the enemy unit(s) with the slider in the editor window? I've tried it using the skill level slider but it doesn't appear to make any difference. My thanks for any assistance you can offer. Regards, Oddball Cactus Air Force
