As of late, I have been playing more Halo 3 over the others. Perhaps it is because it is where I met mostly all of my Xbox live friends to date and bringing it back has just brought back some fond memories. With it came the days of countless hours forging on Foundry, only now am I going back and creating what I could have done 7 years ago. If you find it obsolete, I am sorry, but it won't stop me from sharing the idea in hopes that there just might be a place for playable custom maps on Halo 3 again.
I present to you: Ad Hoc
Ad Hoc is essentially a last minute contingent put together for fulfillment of a task. Which, if you know the story of Foundry, the depots were abandoned after the orbital elevator fell; so, to add to this fictional back story, this warehouse is dedicated to the idea that the UNSC came up with an Ad Hoc to use the warehouses to train new recruits on Draft to fight against the Covenant invasion.
Ad Hoc was created with the same weapons layout as Foundry only to take away two of the spikers and add SMG'S in their place as well as throwing in a particular fav of mine, the flame thrower (with a 3 minute spawn time), just to heat up the game play.
With two well fortified sections for CTF and assault, plenty of open space for havoc to your hearts content, Ad Hoc is sure to keep you entertained and hopefully inspired to create a warehouse layout for yourself.
Let us not forget Foundry
Enjoy
