Apparently, that music file "amb.ogg" was a leftover from Torque3D. It was maybe just a test for map sounds.
I found something else on ecusa. Near the town there is the gulley or gorge with the river at the bottom. I found some trails up the sides, on a ridge, and at the bottom. They're pretty tough trails only suitable for the custom hopper. --- Post updated --- Could you give us screenshots of the map to those trailheads?
I am really hoping that the new maps will have some Easter eggs (especially WCUSA). The cars have a couple of Easter eggs (music playing on the radio and the note in the Pigeon) but nothing really significant, and everything I have found in the maps seems to be unintentional or just well hidden but meaningless. The easter eggs in the Just Cause series added so much to already great games for me, I think it would add a lot of value to the in game maps.
if you launch you're car fast enough off a jump at the top of the lake with the dam you will find a whirlpool about 100yd off the shore that pulls your vehicle down then into multiple layers of a galaxy tubes! best secret ive found so far!
I don't know if these artists are really about death, but their stuff is certainly making my brain cells die.
Ok, I actually just beat that with the desert edition of hopper w/lockers --- Post updated --- Actually, I also beat that with the d35 4x4 once.
