There was a pretty crazy fan-made scenario back in N2 that had the objective as a tank. Some crazy-big gun, TR HMG, and several other components. Rules to modify the tank and change how many points the defender had, too. I used to have this scenario (along with a lot of other stuff!), but my computer up and died on me. Is there some other old-timer who has a copy of that scenario and can share it with us?
