So apparently 343i wont be releasing a beta of Halo 4, in response to this I’ve taken it upon myself to build one in forge world. The map consists of the rear half of the Forward unto Dawn and to have it more like the campaign it will be a one vs seven slayer map (MC VS LOTS OF ELITES)so thats one player as a spartan in green team and the other seven in elite armor for red who begin in one of 3 covenant boarding craft whereas the lone spartan begins in a cryo pod as seen in the teaser trailer. The elites will move from the lower decks up through the ship and hunt down the spartan who will have access to areas of the ship the others cant IE maintenance tunnels, hidden armories etc despite this advantage it should be a balanced match as the spartan is outnumbered.
The map is 95% complete (still need to place initial spawn and respawn points as well as top up the armories and put together a game type)When finished it will be available on my file-share.
Cool map. Send me a friend request. My GT is YouxxGotxxOwned
You should post up a link so you can invite some people to join you to play. 
Sounds awesome btw…
Almost completed, just need to finalize the game type, screen shots available on file share.
