So let me tell you about both the T2 version and the T3 version of LoA

Monsters:

Bomber Zombies: these had me on the edge wondering when or where they were going to pop and attack me. very creative. I loved the Top down Blast Network like view with that room with the statues. very challenging. In T2 they weren't a problem. But in T3 sometimes they would be a pain in the ass to deal with when they were in a respawn totem or a Slag Soldier. Granted i soloed both tiers, i found that the T3 version of LoA needs more then 1 person to do it so that 1000ce rezes aren't being popped.

Almire Soldiers:
I was a lil disappointed when i killed them with ease. They should be as strong as a phantom, they were once soldiers of the most feared and respected army in cradle. I feel they should be a lil bit of a challenge and not just a 1,2,3 hammer swing rotation. I love how they look, always wanted to see them :D

Slag Trojan:
Very challenging, made me had to think about what to kill first. The slags or the ST? its cool to see that enemy type in different places other then FSC.
very good, but are a pain when they are surrounded by the Bomber zombies and they keep respawning around him keep blowing up. other then that great addition

Artwork and Environment:
the artwork is great, from the moment i saw the new Sk lieutenant with the gremlin like shield. with the soldiers all covered in ash in till you hit them, the fire everywhere. the music that makes me feel like I'm actually adventuring again in SK. how your looking for old text inside what seems like ancient ruins. the rooms are challenging and overall i can't wait for it to hit In game
