DESTROOOOY

A stupid looking machine that can clear all stages... with luck

Controls:
IJKL: Forward - left - backwards - right
SHIFT: up
V: Grabber
Z: Frontal Bomb
X: Back bomb

Note: Machine is a lot more stable without the bombs and works perfectly well while ramming. Just watch out you don't light itself on fire.

This small army is designed to take out maximum targets without risking your whole machine. The army has two Kamikaze bombers (back left and back right machines), a payload delivery vehicle (far left), brings bombs to the enemy then can detonate, an armored catapult (far right) and finally a multiple bomb thrower (center) that can be used to also reload the catapult.
Controls:
Right Bomber - o flies it up and forwards, n releases the bomb
Left Bomber - p flies it up and forwards, m releases the bomb
Bomber Truck - t/g/h/f are forward/back/right/left respectively and y detonates the bombs
Catapult - z lowers armor, b launches bomb and i/k/l/j are forward/back/right/left respectively, q will self destruct
Reloading Car - use arrow keys to steer and numPad 4 and 5 to curl arm, >. key extends arm, numPad 0 rotates bombs

I made this simple rover with suspension as a base to build upon. The idea is to have an all terrain platform with speed and good steerability.

Made by my Friend Timo (Xenomorph on Steam)

Controls:
Fly=o
Fly up=Down
Fly down=UP
Fly Left=Left
Fly Right= Right
Drop bomb=V

Up and down to move. Also in the differential gear itself, I've attached two springs that contract whenever you press up or down to keep the gear tight.

Shoots anything but sets it on fire. shoots archers mwahaha

Bolt-Action Rifle containing 3 shots.

Left and Right arrow keys to rotate the bolt handle.
H to toggle bolt open and closed. (Can also use L to assist in opening the bolt, and K to assist closing it).
1, 2 and 3 will fire the first, second and third shots respectively. The first shot is readied after the bolt is closed. Once shot, use J to move the rounds up, open the bolt, and use Y to eject the casing. Close the bolt, fire the second shot, and repeat, but this time using V to move the second casing up. The third shot cannot be ejected.
