So I was just thinking about it and I think it’d be friggin sick if 343 made Halo 4: ODST and with that came DLC for ODST armor and possibly even more armor like Mark V and CQC and Firefight could return with more features than ever!
ODST 2 would be more of an open world type shooter with plenty of things to explore, side missions to complete, collectibles to find that include weapons and upgrades for your armor, and -Yoink- to blow up!
What about this? There’s a leveling system in ODST 2 in the campaign, RPG style where you can spend skill points to increase certain things like reload times and movement speed, this leveling system can also get you things in Halo 4 like the full set of ODST armor or Mark V by getting to a certain level.
The gameplay could similar to that of Far Cry 3 where you can approach most any situation how you want to, you can go in guns blazing with a SAW, sneak around taking the entire base down without noticing, use teamwork to take bases down, and more!
There could be multiple different armor pieces that all give you certain attributes such as some sort of Sniper armor where you get less recoil for semi auto rifles and snipers but less accuracy with everything else, or something like that. These armors would be obtainable through finding them, completing a certain amount of missions/certain side mission, or buying it through some sort of store.
Possible Firefight Maps
Plantation
Set on the mountain range farmlands of Reach
Lost
Ancient forerunner ship lost in deep space
Railway
Large circular map with multiple stopping points and a train to take you to each point
Malfunction
Malfunctioning holodeck where the location, time of day, and background changes every once in a while
Shipwreck
A Covenant cruiser that crashed in the jungles of Africa during the Battle of Earth, the cruiser is now covered in vines and foliage which would look friggin awesome.
Rooftops
Three rooftops connected only by the cranes in between them.
Quarantine
Flood infested swamp like the one in 343 Guilty Spark
So what do you think? Because now that I think about it I’d friggin love an ODST 2
