What I have set up for the ammo now is there's a crystal inside the base. Ammo is represented by gas, and you get 28 at a time, then when you run out, your marine turns into a civilian until you get more at the crystal. Anybody have any suggestions for other quests? I could actually add in an "assault on (bug homeworld, can't remember the name)" part using the pylon psi-field sprite, so everything within a certain area looks blue.
Of course, now that I'm testing it in multiplayer, I suddenly discover "oh, the 'pause game' trigger doesn't work in multiplayer!" great.....I'm having serious trouble with the cinematics. It's gonna be 5 player when I'm done, and probably take at least an hour and a half to play.
ADDITION:
Alright, now I've got the "wall attacking effect" working. It looks so cool. I put a bunch of wall traps along the wall, but gave em to player 6 so players can't click on them, but the bugs attack them, so it looks like they're just ripping panels off the wall. And after they destroy a panel, bugs on that location get teleported up onto the wall. This is gonna be such a sick map!
ADDITION:
I'm also going to add in a "landing" quest, where there's 5 Battlecruisers (1 for each player) and players have those blue energy balls coming at them, with gaps to maneuver through. I'll use dying corsairs for them. And you have to get at least 1 ship to the landing site. I'm also adding in a "life-counter" each player will get 3 lives (respawns)before game over.
