Playing with my outfit (years ago, can't remember the name) in PlanetSide.
We hijacked an enemy Terran Republic Prowler (big tank with dual 100mm cannons and a pair of 20mm machine guns) on Forseral, one of the game's earth-like forest worlds. It was just the 3 of us, me in the main gun and the two other guys controlling the tank and the machine gun. Every time an enemy Reaver would swoop down at us, we'd hide in a forest and wait for him to peek down to find us, at which point he'd get a pair of 100mm slugs to the face. After about an hour and a half of this, we had 50+ kills, had no ammo, and the ENTIRE TANK was covered in bullet holes. We arranged a deal with some poor hapless Terran MAX we ran over; we would give him a ton of our own weapons in exchange for ammo boxes for the tank's main cannon. We met inside a warpgate (neutral zone which can teleport you to other maps, you cannot fire weapons in it), made the deal, then set off again. Eventually the Terrans started to push back at us, so we had less and less room to maneuver and hide in. Eventually, we got ambushed by a pair of Reavers which forced us to go down a road - full of mines and infantry. We went down in a blaze of glory, shooting anything that moved as the ground exploded around us.
