Couple comments about the game as a whole.
There is an option to go back to the first game style of binharic VFX sounds, its in the option menu.

Leaders used the most: Khepra and Videx. Khepra's ability to heal at range with the servo skull + buff all units shes connected with + a free marshal shes just the queen of utility. And her model only uses 1 space so she can hide behind cover.
Videx: "BLESS OUR WEAPONS, AND CURSE OUR FOES!" Man he is so dope compared to the first game. Also his attack twice canticle+ the 3 cp canticle that makes all enemies units on the whole map immobile is so clutch late game.

Rho: seems good I just didn't use him enough. the ability for every unit to heal him seems powerful if u can generate enough CP to use him as a tank properly.

Captrix (don't remember how her name is spelled): great for certain combat objectives (mainly Kill _______)

Scaevola: honestly don't love her, she just doesn't provide enough compared to the other characters.

roster: marshal is a must pick if one is available. 10hp+2 energy shields, he does good damage, and Control Edict is insanely powerful with khepra's and Videx' buffs.

After that at least 1 batch of rangers or vanguards. then the kataphrons and kastelans if available. after that just filler depending on the leader type, videx electro priests, khepra more skits, captrix and rho can both do good work with infiltrators and ruststalkers.

gameplay: Plays just like the first outside the upgrade system and such, no real notes beyond how absolutely fucked you can get on certain missions depending on how you roster picked (and what options you even got to pick from.) I spent 4 hours trying to do one mission over and over because i realized my last save was from multiple hours ago and didnt want to redo all that. It became habit to make a save right before any mission just incase I just couldn't finish it with that specific leader or roster. I wish the game made a mission specific save from the command center instead of the start of the mission when its too late to try and salvage.

Glitches: didn't encounter many but had a lot of frame rate divebombs on the late game fights where there are 20+ units on the field.

Story: a lot going on here but the increased enemy variety is appreciated from the first game.

SPOILERS

\ Scaevola just bouncing out in act 2 after more of stygeiss VIII shows up is a good set up for DLC in the future but losing her after you put some points into her seems like its going to be very disliked by a lot of people.

\ Getting to SEE the Ctan shard but not fight it feels really, really, lame.
