This man made island is a destination spot for combatants who like a few options when it comes to invading their enemy. Heavy tree coverage leaves plenty of room for ambushes and sneaking past patrols.
Each player starts in an easy to defend "fort" with a central access path that can be defend via two raised outposts on each side.
But don't spend all your resources on shutting off that one route, two side roads can be opened up well out of range of most defense on the outposts to allow for flank attacks on the base.
Multiple paths diverge all over the map, any route that your opponent blocks off leaves others open to attack on.
Rich mineral deposits sit close to home but in an open field and harder to defend then the two normal island expansions that sit further away.
Control of the Xel'Naga towers will give a significant advantage to knowing your opponents troop movements.
