River Crossing is a 2 player multiplayer map in StarCraft.
Overview[]
The two bases have different defensive options. The top one is close to an arena, forcing enemies to go around. The bottom one is more open, but features a choke point further up. Air support isn't absolutely necessary, but certain resource fields can only be accessed in this manner.
