Leave it to Spikey and his train obsession to create (I think) the only playable train-themed CTF map Red Faction has seen

Spikey, the Red Faction Community's resident train connoisseur, really nailed the "stock RF theme" with this map. Martian Subway explores an area of the Ultor subway system that wasn't visited in the stock campaign. It appears to be set a short distance away from the Miner registration area of the complex, judging by the barren outside area directly above the subway.

In the gameplay department, Martian Subway pretty closely follows a basic square grid layout and features plenty of space in which to fight. You won't get lost - though you may get run over... repeatedly. The item layout is solid, and the "spawn rooms" are an interesting touch I haven't seen much in other maps.
