Walkers must be tag teamed, very hard for an engineer to beat a good walker 1-on-1.

There are vents underneath the walker. If you fire your assult rifile or whatever into those vents you will damage it a lot.

Cool thanks. Vents underneath. interesting.

Scroll down, I link to a thread that has pictures...not sure if the posted thread in this thread is the thread Im reffering to.

woo.
