Starship Troopers Extermination. This is why we bring knives to a gun fight! Secure Ark and Horde 

This is two videos, the first video is Secure the Ark (easy) from quick play, and the second video is Horde on Hard on Valaka. Running out of ammunition for the whole team and everyone is left with only their knives and grenades. Words of advice for the FNGs, find and kill the bugs who belong to the wave (usually stuck somewhere) or else you end up using all your bullets.
