As the title says, what about a third Warzone mode called ‘Warzone Firefight’ which is 24 players versus an army of Covenant and Prometheans. Rewards could be round or set based in which you’ll get your REQ points and after every round/set, the more sets you survive the higher the REQ/XP multiplier. REQ stations are of course present in this mode and would work great with Firefight. Players have to capture strongholds to make REQ stations available to themselves and have to defend it from enemy AI trying to take it back. If a stronghold is lost than so is the REQ station The game ends once the final set is complete and the surviving players get bonuses. The idea has great potential but needs to be fleshed out, especially when 343 is actually considering a PvE mode
I know there are other Warzone threads around but i want to focus on the Firefight idea specifically.
