Halo Wars 2 Blitz Strategy & Tips
Use the High Ground
Halo Wars 2’s Siege and artillery units LOVE the high ground so take advantage of those areas provided by The Proving Grounds. A point that is guarded by a line of units such as Locusts and Blisterbacks is brutally difficult to break. Cracking through a well stacked siege line will require a team effort from two players and leader powers. Even if the enemy is eventually able to break through (and many new players struggle with that feat), they will likely have needed to sacrifice lots of units and energy to do it.
The best part about this is that the longer your opponent waits around to move in on your siege line, the harder it becomes to break. You can either keep saving up energy (and score if you have the point advantage), or continue to add on more and more siege units to make it nigh unstoppable while your opponents make up their minds on what they want to do.
