Got it thx guys. Got full IB gear now

Lol it's a level that is on the Mars map. It will be the first one you do, you start out in it turning on a terminal so you can link your sparrow and be able to use it. Right after you link your sparrow a big door will open. It's going to be a total of two drop ships. The first drop ship deploys red enemies, your choice to kill them. If you run right past them the second drop ship will drop around eight yellow enemies. Kill all of them leaving one guy alive (I usually leave the jumping shielded centurion alive). Wipe and repeat after you respawn. To do this correctly you should have it on the next difficulty up from normal. I think it's level 22. And make sure you use a resupply code for the extra glimmer. Enjoy!

You're excluded from it.

Put on lvl 22

It's a mission on Mars. A lot of cabal majors spawn there.
