Vertigo was one of my favorite halo 4 maps with the 2 towers you could fire at and strip the enemy team shields. The map was very open with two flank routes and had mid where rockets spawned in. I think that this map would fit in infinite very well.
I don’t think we’re gonna see any substantial map additions until around the time Forge is finally complete and shipped. Halo 5’s Forge was insanely detailed and I’m sure H:I will be an even more robust system. Give it time and we’ll probably see all the maps we know and love.
