Yes… this guy has a working sentry gun. I want one…

Call me when It actually shoots something (Rather than Track it)

It didn’t even shoot missiles at him…

How does it shot missiles?
:3

Missile launcher

Needs a bit more in the way of doing stuff.

you guys could show some more enthusiasm

also you are killing the mood.

Needs a paint job though.

DUUH. This is so …
HURR DURR

Awesome.

Sentry doesn’t shoot and no one is sappin’ it, video fails twice.

And it tracks everyone, if it was like a proper sentry, it would only shoot those wearing the uniform of the opposing team.

I like this one more
