Some new objects for Forge that may be usefull

Realism could be helped by some interactive objects such as:
-Elevators
-energy/light bridges
-doors
-ladders
-alarms
-any others

Also some destructible objects would be also cool to have and maybe have a value to determine if the object is destructible or not some examples may be:

-walls
-gates
-bridges

Here are some other things that would be nice to have in forge:
-AI
-Turretless warthog, transport warthog, ability to change the color like a snow warthog
-Elephant
-flames that may or may not give damage
-bombs/mines that you carry and can set

this would really be a good idea, also maybe stuff like light bridges like in halo 1, really the new halo anniversary maps should have some new cool forge options, also in halo 4 i believe they should add really advanced stuff like terrain editing
