Q: Are there rules for facing in the game? 

A: No. When this game was originally played, we didn't even have proper miniatures - we used polyhedral dice to represent our robots and, as such, we didn't really have any way to indicate facing. The lack of facing didn't impede our fun, however. 

Q: Are there rules for cover/difficult terrain/other battlefield obstructions? 

A. Also, no. Not only did we use polyhedral dice to represent our robots, but we didn't use fancy battlefield terrain. That said, adding rules for obstruction and things like LOS (line of sight) on the go is pretty easy.
