No! Forge World on Halo: Reach is completely free, provided you have the game and Xbox to play it on!
You might like lost planet 1 or 2 or section 8 which are games very similar to the halo series. <i was asking for a game with a similar mode to halo reach's forge mode
You can't set the time limit in forge
Yes, there are custom game lobbies, creatable game variants, and a different variation of the one in halo 3. This different variation of forge is a little different but alike in a lot of ways. so yes there will be forge.
Yes, but you'd have to have a timer on for the game.
You only get it when you are doing forge mode
at the beginning of the game before you start it, put game type: oddball in game options.
Yes, Halo Reach does have a Forge mode, it's found in the main menu. Further information: Scroll down in the main menu until you see the Forge option, select it, and you will be able to choose which map you wish to edit by selecting a map, you then make sure that you have put the setting on basic editing so you can use the Forge editor, then have fun playing with the forge! Happy editing :D
invite more players to your game and tell them your design of the map that you want to create
I would say Forge, depending on your amount of activity.
You can't unless you mod which can miss up the game hope this helped.
play a forge created game that has the upgrades placed in the map, or change the game settings in a custom game.
