I didn't get helioskrill once I met requirements.

I completed all halo mcc campaigns in legendary and didn’t receive helioskrill. Please help.

Check your game level history. Sometimes there are levels that don’t register as completed. If one isn’t showing completed, go back into it from last checkpoint. You may have multiple levels you have to do that with. There are a lot of discussions and tutorials on this topic floating around.

Quote from a Monitor:

> Go back to MCC. Change your multiplayer armor, or your emblem, or your banner, or something. Make sure the game saves the change. May help to play a multiplayer match. Then open the Halo Channel app. Then finally go back to Halo 5, and check your collection.

Just keep playing H5. You get it in a Gold REQs eventually.
