Found this info over at
Total BF2142
I've never tried Sandbox for
BF2, but from what I understand, this mod allows you to spawn any
object in the game to build whatever your heart desires.
A few notes from the creator can be found
here. A few things to note:
- all the features work just like BF2:Sandbox, except for loading/saving.
- To spawn objects the player must type the objects into chat rather than use of the coma rose.
