So I came across
this gem the other day, and thought I'd share...
It's essentially a 4-meter tall robot that has two gatling guns that fires 6000 BBs per minute (which is activated with the pilot's smile), among other "weapons". Imagine this bad boy in the next Nightfall...
If anyone wants to be the Batman of airsoft, this is where you'd start. However, it costs a hefty USD$1.35M (starting price).
