SupCom 2 has many hilarious Experimental units, all of which require massive amounts or resources and time to build, but they turn out to be worth it, not only because of their power, but also for the intimidation and entertainment factors. It’s hard to pick a favorite, but the Noah Unit Cannon has to be the most awe-inspiring. It’s sort of a building, since it doesn’t move, and it builds other units. It looks like a pyramid with four transparent “barrels.” You construct units inside it - say a few tanks, a few anti-air missiles, and a few artillery. As the units finish constructing, instead of popping out on the ground next to the Unit Cannon, you can actually see them loading one-by-one into the barrels.
Once you’re ready, you designate a target point (it can be completely across the map), you click “launch,” and the glorious Unit Cannon fires off its payload. It's hard not to cackle in glee as tanks and artillery go arcing across the map, landing miles away inside the enemy base, and, of course, your units instantly unload their weaponry on your stunned opponent.
