I've tried starting in devmode and using con_restricted 0 but nothing's made much difference.
When I try using godmode 1 the confirmation text g_godMode = 1 [ ] comes up but I can still kill and be killed. Any other commands to change the suit functions just don't work, the text that appears after I type them in confirms that they haven't been activated.
Any ideas, or am I just doing something completely wrong?
