Yes the mod can inject 3 additional people in the campaign resulting in 16 players when 4 players do it, it's amazing lol.
Sadly not possible for campaigns that only can do 2 players resulting in the max being 8 which is still alot.

I might be remembering wrong but I think I saw some people doing 16 player Halo Reach campaign as a side effect of that mod which looked chaotically fun.

With the new alpha ring split screen mod I'm actually doing a irl lan party with modded maps, I think it'll be very fun.

You're right, I've had fun with every Halo. Including 4 and Infinite (Don't care for Halo 5).

Literally all of them are except for 4, infinite and 5

Where are the trump impressions?
