It was, by far, the largest map I've ever seen. Mine a shit load of Morkite, kill some Fleas, and there's Gold Rush. But oh, also Low O2.
We played for almost two hours on one map, because of the constant stop and wait for air. Along the way, we killed _6_ Detonators.
Based on past experience in cave systems that big, we'd learned you don't just call for evac right from where you are, because we've seen the drop pod be so far away the Mule can't actually reach it in time and it just teleports it, leaving you SOL.
So we retreated back through the cave system a good ways before calling for evac.
And immediately guessed the wrong way and started moving as soon as it arrived. We all start heading the direction we think we should go, before realizing the Mule isn't head back toward our initial insertion point....it's heading back to the bottom.
Panic sets in immediately. Scattered, we scramble to catch up to the Mule for its oxygen. One friend goes down, and I immediately dismiss the idea of rescuing him. We have no resupply, I'm on the last dregs of ammo, AND I'm running low on O2. I grapple gun my ass off past swarms of bugs, racing to catch up to the Mule. I reach it and replenish some O2 when my other friend calls out "Oh god, don't fall in the hole!"
I grapple gun again right into the darkness and as I'm coming off my line, I fall DIRECTLY into said hole, waiting there right in the line of our evac. And right about this moment the friend who shouted out says he's down.
I start falling, and it's a loooonnnnnnggg fall. I hit the wall and take a shit load of damage, about 80% of my life, skip off it and start falling again. I figure this is it, I must have plunged down one of the holes created by our resupply pods that have swiss cheesed the map, and our run is officially boned. But on instinct I take out my grapple gun and fire it at the wall just as it comes off cooldown, locking on. That's when I notice the sheer SIZE of the hole I fell in. I look down.
And straight at the roof of the drop pod. I'm about a meter? above the ceiling of the cavern it landed in, literally grappled at the absolute last second before plummeting to my death. And sitting next to me, on a little ledge just outside the drop pod hole, is my friend who'd fallen in ahead of me.
I rez him and we get in the drop pod. We briefly consider getting my other friend, who is only 40 or so meters away (somehow) with several minutes left until the pod leaves, but the 7th Bulk Detonator of the night making directly for the pod puts paid to that idea, and we just evac.
16k gold and 16k experience for a 2 hour run. And the last second panic grapple was literally the difference between a victory and crashing to my death on top of the drop pod in shame.
