Well, the title.
1. the green/gray train. I admit, I use the colours from another player, but there isn't copy, I have being modelling the train hours for what? nothing, and I explained that is for map porpouse.
And now the vending machines...
the rule "not inappropiate content or stolen from other games". There is a HL2 vending machine come on. But recognising easily two VM, one for water supply, and other for food. Where's the problem? I choose even without trademarks avoiding legal problems to the personnel.
