how do you get that
if you're talking abotu inf marines/hornets than this is how...
get 2 players on the covenant, can be from rally point alpha, kill all the enemies on the island with the AA wraith and leave 1 player there without a hornet, have the other player fly onwards until they get a checkpoint then fly to tower 2, land, and jump off the edge, a new hornet would have landed on the island by now, along with a marine pilot, take that hornet to tower 2 and land it, wait for the new one to come and jump off the edge, keepp doing this until the game lags so the hornet spawns wihtout a pilot and will just fall, if you want more marines destroy the hornets, if you want more hornets kill the marines, because it's on co-op you can kill yourself as one player and spawn wiht weapons again you can arm the marines, i like to give them carbines, brs and ars because they put them on their back, plasma rifles are just lowered, you can kill 2 of them and they will start to fight you, after a while you'll start firing blanks so just melee one pilot to get your weapons back, kill 2 and get into a hornet and kill them from there, they are really powerfull even on easy because theres so many, even if you're in a hornet...
Oooo , somebody is going to lock this!
and what makes you so sure about that?
