Finally! We have reached a point where this game can be called finished in a prototype sense (or the point to gain the first study credits from this).
All parts that were planned are readily modelled, textured, and functional. And on top of that, there's now sounds and music! There is no multiplayer mode so far, but the player can fight an AI enemy. While the physics are not perfectly balanced out yet, they work pretty well and already allow for rather exotic constructions like the one on this video:
Parts that made it: Wheels, Propeller, Jet Engine, Rocket Launcher, Flamethrower, Saw, two kinds of rotatable joints and an extendable arm part, a head part that turns with mouse view.
Parts that didn't make it (yet): A "jammer" that shoots projectiles making the enemy parts perform random actions, an anti-air homing missile.
There will probably be a downloadable version for this blog.
