Callosum

1v1 map with numerous tactical options. There is the high yield expansion that gives dominance over the main battlefield; the secondary battlefield accessed through rocks that allows flanking entry to the enemy's main; and most notably there is a path directly between your main and the enemy's across a narrow bridge covered in destructible rocks. Close proximity of bases also allows for deadly air harass tactics, and island expansions allow for safe fortresses from the enemy.

That's the plan, anyway.
