Beach Base

 is an arena in Block N Load.

Summary
With Beach Base, there's a lot to explore and there are many possible attack routes to create. The narrow bridge linking the first Cubes seems like the first route to try the opposing side is likely to have thought of this. Perhaps making use of the small islands could help to form part of an alternative route. With the final Cube Core on either side set atop a broad tower it may seem like a mountain to climb to get to it, but a few blocks dug out and a few more built in the right place can create a rapid route for either side to reach these final points.
