I remade Halo 2's level Foundation. It was one of the first maps I made. I never knew abut unlimited budget and wasn't that good at interlocking, it still is a not to bad map though. All the weapon are the same except the SMG has been replaced. In Halo 2 the four symmetrical rooms were numbered, in my remake I used Overshields, Active Camoflauge, Custom Powerup and Reciever Node to create a similar effect. The level has been built so that is hard if not impossible to escape. Its been set for every game mode including Infection.
Here are the two screen shots taken that show the level from Side A and Side B
