Blood River

Blood River is a multiplayer map for Halo Wars, added by the Historic Battle map pack.

The map features two opposing regions cut in half by a river, which could only be crossed with two bridges, one of which is light bridge. The starting bases are located atop the hilltops in the opposing corners. There is a Forerunner supply elevator on each side of the river, both featuring deployable lookout towers next to them. Additionally, each sides of the map feature a Forerunner secondary reactor and a base site (initially occupied by a Forerunner fort). All three sites are defended by Aggressor Sentinels.

Strategy

 * A good tactic is to hold the two bridges; if the player can gain control of them, enemy ground forces would be prevented from reaching the starting base.
 * On the other hand, another good tactic is to rely on air units to make the two bridges irrelevant to the ensuing battle. But if the player chooses this tactic, their base is vulnerable to a large-scaled ground assault.
 * Both bases are situated on top of hills, so long range units can annihilate enemy forces coming up the hill if put in the ideal locations.
 * There are supply elevators located next to both bases, they are a good idea to garrison as they also act as a good defensive position.
