In case the TV commercials, product tie-ins and internet chatter haven't alerted you: Halo 3 comes out this Tuesday. One of the features we most look forward to (other than killing your noob ass) is The Forge, Halo 3's level customizing utility.
Bungie released all the details yesterday, and it looks smokin'. It allows group editing and on the fly maniuplation of objects and vehicles in what sounds like a very intuitive interface. You can then save and share your map because you are a generous person.
Finally our dream of a level with rocket launchers on every square surface inch will come true.
We like rocket launchers.
