Would be nice to have a harder version of Firefight for Matchmaking.
Maybe not just Legendary Firefight but also just allowing more enemies to be spawned in at a time and faster enemy respawning, i’ve said this before but alot of the time it feels like you’re just waiting for the next wave to spawn in, this is true for both Halo: Reach and Halo ODST Firefight.
Alternatively asynchronous Firefight with 4 Spartans/ODSTs fighting against the regular onslaught but also having 1 Elite player Fighting alongside the AI would make for a fun challenge, this is already possible in Halo Reach Custom Firefight, would be cool to see it in Matchmaking.
