Well, I don't think it's gonna be a "Battle Royale" game. While by technicality a BR game is a massive multiplayer online game, I think they mean MMO in the sense of like Anarchy Online or WoW or even Star Wars Galaxies.
In which, I think they'd have more luck with a Marines Only Survival game instead of that cause let's face it.
The aliens won't be brutal and scary if:
1: You got typical MMO Gameplayer where everything is a bullet sponge.
2: You got typical MMO gameplay where death is just a little hurdle and nothing to worry about.
3: You got typical MMO gameplay where "You're the chosen one" bullshit.
4: You get the typical MMO AI that is ass.
5: Third person will everything on your HUD being cheaty...
Cold Iron, if you read shit here... Here's some ideas for ya.
If it was:
1: First Person only with no HUD
2: Tracker is a tool not a HUD element, along with Compass, Watch, Map, ect.
3: Primary Story based on Character and death limits (5 allowed daily deaths and no you can't "Buy more lives". f**k MTXs), Permadeath on special operations.
4: Death is fast and visceral as hell for both aliens and marines.
5: Classes (Medic, Smartgunner, MARSOC, Pilot, Combat Engineer, ect.) each with their own kits and required (Player)skill to understand and operate. No "Do it all" types that make games unbalanced solo-trash.
6: A "Alien" character that can be used in "Control Zones" for those who wanna do that, or focused "PvP" arena matches inside of Hives for "Simulated Battles" (You know, for the Care-Bears).
7: Primary Cosmetics are unlocked through GAMEPLAY not Microtransactions. Cosmetic Microtransactions are okay as long as it's not lootboxes and core-lore equipment. No Pay To Git Gud.
8: A Before You Buy trial period for 7 days (With no walled off content) to allow you to explore all classes on several individual characters to find the playstyle you love the most.
I'd pay out the ass for that. No questions asked
