Cell +

I recommend a cell + mode. 4-8 players with increased difficulty. Not necessarily nightmare mode, shield recharge is nice. Maybe twice the number of enemies with +5 to their level.

Lag, lag everywhere!

before they can do anything awesome like that they gotta make it so hosting doesnt destroy someones computer :X

So you would host for all the people without 1st world internet 24/7. Seems cool.

AFAIK the game engine does not do 4++ players + enemy AI well (AI totally unresponsive, waves take 3~5 minutes to 'load'). Hence why the reluctance to even address central hangout open sandbox areas and whatsuch.

 

So making 4++ player modes would require either:

1) change to a different, MMO-like game engine entirely

2) revamp it with decentralised enemy AI-handling

3) make large area, but disable enemy AI

4) turn the game to server-based AI instead of P2P

 

Do any of that, and I'm afraid the resulting game won't even be Warframe anymore :/

 

I mean, why bother doing standard 4-Tenno cell raids if you can run with an entire Ghost clan?

I recommend you use Nyx Mind Control on mobs and you will get extra player for your team.
