The Sandin map was kind of a concept for a standalone game I'm seriously planning to make in future. It would be like the old army men games crossed with Battlefield and with environments similar to AirFix Dogfighters and Rats for counter strike. Although there is a new indie
army men game coming out, what would set my game apart would be a heavier focus on large scale multiplayer, vehicle combat, a first person perspective and a more hardcore damage system. It would be an army men game, but it wouldn't actually have any relation or play like any of the old army men games.
That game is a while off from actually existing though, but with the way games are going with kickstarter and steam greenlight its definitely possible.
