Anti-Air MK1

I Can't say too much, if you press J, the Cannon aims at your mouse pointer, if you press K it activates a Laser Sight and when you press H, KABOOM!!! Bye bye mr plane, this can down planes, but it's no the best one, There's also the MK3 Anti-Air, which is better.

If You're asking about the MK2, he's a bad project which has never come to life without an error.

So, here are the control (Again):

Press J to Aim
Press K for Laser-Sight
Press H to Shoot

Enjoy your Anti-Air Cannon MK1!
