I've previewed my bonus techs in this post (a couple more movie/game reference builds, menu brawl techs, etc). They continue below (damn the forum's 6 embedded images limit, heh):
"Field Arty" - a silly little canon on wheels, like a WW2 field artilery piece (Howitzer or something).
"Flatbed ADF" - HE level 2 only tech with a bed of mortars in the back. (Not ideally mounted, because of trying to keep a low profile over the awkward wheels.) Alternative version of the feature resource carrier, which could also be used similarly, just removing the mortars.
"Arachnid Pylon" - based on the wheel base of an old submission - "Sniper Mantis". (Unfortunately the Weapon Pylons are level 3 blocks, otherwise it's level 2 weapons on a level 1 base. Bit of a weird mix.)
"Harasser 2" - A rework that should replace my old submission "HE Lv1 harasser" (@zanzistar) which is no longer capable of staying upright, due to wheel buffs and/or physics changes.
"BracketMobile" - A concept supercar with jet engines and guns... So basically a Batmobile. But made of only level 1 blocks! Stylish and actually fun to drive - does doughnuts under thrust.
Small note for @Matt (as I'll probably miss the stream) - watch out there's a few Creative save games submitted, above, that aren't noted as such (or previewed). But it seems that the game will now throw a (somewhat vague) error message if you put them in the wrong folder anyway, which is handy.
Here's my submission for the Community Core Submit...
R&D Save attached to this post with 4 Hawkeye techs. The 2 vehicles have thrusters, the 2 mechs do not. Enjoy.
cipher Skirmish: small vehicle loaded with 10 Zeus Laser Canons, angled downward to use thrust.
cipher ManticoreTank: good sized tank with a variety of weapons, utilizes rotor fans for increased speed.
cipher Nightmare: meant to look unnerving, plenty of weapons but weak defenses.
cipher Assault Mech: massive weaponry and decent, but not perfect defenses.
YIKES! That it does! It's an H. R. Giger abomination. Like a mad man grafted an airboat propeller to an Alien with feet morphed into giant spiders and it's coming to get you! (Given smooth terrain.) Great builds. Everyone.
