Fire Chasm BETA
Well this looks like a pretty cool "target tag" map - it may only be in beta, but for a while you were welcome to try it out yourself by taking a trip to www.idrive.com/nabdotnet, and downloading the file from there...but I think it has gone from there now.
The traditional two forts face each other, and there is a chasm across the middle of the map - this screenshot doesn't show the lava at the bottom of it, but you can see it pouring down to my right! You can see the footbridge that spans the split - but both forts have a big cannon trained on it, and if there is a gunner up by it, ready to press the firing button as you start to cross - goodbye! An earlier version of the map had the "explosion" on the bridge nicely visible, but the effect is still the same.
But tunnel into a fort, check out the target-triggers, the passages, the armoury...open the gates from within, or just explore! It is a fun place, with some interesting balances!
