I've used Tibed, I tried giving sonic tanks devastator shops, so I made a new copy of the devastator weapon, and edited that. THe game wouldn't run (I checked those warhead number numbers). Stuffups also occured when giving flying units sight range (fast exploration). I made airstrike build very fast (speed 1000), and it worked (quite well). Might bother to send in a screenshot to dune2k.com sometime. Raider trikes with gas warheads are fun too, you get a nice coloured cloud where you're shooting. Invulnerable sonic tanks are even better, with a speed/damage increase. Surrond the base with them for defense, send about 10 on a raid (cheap/fast), and it's guaranteed to destroy whole bases (unless they're atreides, in which case, the game is stuck). Adding units would be great.
