Not much has changed here. Enemies spawn, adds will kill you if you’re not careful, there are three pieces, but you do have a new obstacle to deal with.
New mechanic: SIVA enhanced Walker spawns in front of the bridge onto the ship.
Believe it or not, this part is as easy as you might think it is or is much easier than you might think. Start by performing whatever tactic you use to beat normal until you make it to the walker. I suggest taking out all the adds or hitting them with smoke/tether and then focus on the walker. All you need to do is break one of its legs, ignore it and walk onto the ship. If it gives you further problems, simply break another leg to walk past it.
For the person jumping on the Siege Engine I strongly suggest going as far left as possible. Less mines/enemy attacks that way. I also advise killing the adds while you’re on the ship.
Aksis Phase 1
This is arguably the easiest part of the whole raid.
New mechanic: There is a SIVA turret on each side.
This is really as straightforward as it sounds. Kill the turret, fight adds, wait for the turret to revive, destroy it, kill the captain, find your servitor/destroy the turret, destroy the servitor/throw the bomb, meet in the middle. If you can pay attention to the turret and kill it every 30 seconds or so, it will feel like normal mode.
Aksis Phase 2
Remember the final part of Aksis’ first phase? Well, it was just training for this part.
New mechanic: Seven SIVA charges are required to break his shield.
This is really as easy as it sounds. Do the fight normally, but instead of stopping after one servitor, repeat it twice more. It shouldn’t give you any difficulty outside of the stuff you faced the previous round. Aksis also doesn’t have a huge increase in health, meaning it is still possible to drop him in two phases or three relaxed ones or even five really lazy ones.
