first video is "Infinite Weapons Test Demo" !-)
what was the TNT button, is now a more general WEAPONS button. for choosing from the available weapons carried by your selected miner. thus also now, your first two smileys improve your senses, then each extra one taken gives your miner an extra random weapon !-)
in FUSE BOMB mode, you'll see a fading bomb showing where the bomb will be dropped, if you press the left mouse button. also, fuse bombs can be pushed, so as to be dropped down mine shafts ... but do be sure to get out of the way before the fuse runs out ...
BBBOOOOOOOOMMMM !-)
in LASER mode, you'll see a fading laser spot showing where the laser will be fired from, if you press the left mouse button. have fun blasting away!
