Nah if we're waiting on somebody I'm usually busy filling the drop pod with decoy nades. I'll call a whole resupply about it if I have the time and the nitra.
Remember: management takes away any grenades you haven't used by the time you come back up. Might as well toss them all somewhere so they don't think that you don't need them.
spend all the spare nitra (snacks for Karl), throw all grenades as a garbage way to hold the door for the last dwarf, spam Rock and Stone until the game stops me.
