NOT red alert related
A simple vehicle aimed with the mouse, with near-flight capabilities(no, it can't fly too long).
Controls:
Left and right - vehicle movement
Down - Retract legs, Engage downforce crouch mode
Up - Motor thrust, Extend legs(for jumping - the thruster is not powerful enough to lift the machine)
Mouse - Aim machinegun
Enter - Fires machinegun(1000 round ammo storage)
it's able to complete the course in less than a minute.
for the strategical part, you can try to jump over it(hovewer, chances are you'll not get over the laser), and also engage crouch mode while zipping past the entry at full speed(it's able to dodge completely the sentry gun)
