This week’s dev diary into the inner workings of Machine Gun Jetpack explores the world of vehicles – the handy and totally awesome rides that Barry will commandeer during his daring flight!

Lead designer Luke Muscat and lead artist Sierra Asher explain some of the finer points of the MGJP vehicles.

Halfbrick has mentioned over at a TouchArcade forum thread that Machine Gun Jetpack is set to be submitted any day now and aiming for an early September release.
