Here's a new Duke Plus video:
http://www.youtube.com/watch?v=iwN10FeQjI0It shows some old stuff, like the breakable glass pane sprites, transparent water, mantling, snow, ladders, working cola machines, jump pads with destination arcs, etc. It also shows some new stuff from the upcoming 1.7 release, such as the in-game options menu, the gravity gun (now with saw blades ), timer mode on pipebombs (they can toggle between trigger and timer), and the MIND BLAST, which is the alternate firing mode of the shrinker. The mind blast temporarily converts monsters so they fight on your side.
I have already fixed two bugs that are on display in that video (jibs burning for no reason and the gravity gun picking up nearby objects that you aren't facing).
