I have just complete a full run. I say “full”, but the ending gives a strong hint that there is a different, “true ending” which may take multiple runs to reach.
Things I am liking . . . .
Seems like there is a lot you can do differently about assembling a lance of mechs. Different chassis (body), transport (legs, wheels, tracks, jets) and weapons and buffs. I read about various mech designs and lance designs in the steam forums that I have not even touched yet.
Meta-progression. Not everyone loves it, I do. I welcome that there is a progression treadmill to help me feel like something useful is happening just thanks to playing, win or lose. In this game, your meta unlocks new research that can enable new mech parts and passive buffs for future runs.
Tactical combat. Simple but often quite thoughtful, and again, quite a few different ways to approach it. Some for example, avoid ever getting hit, but you can also use damage reflecting shields, mines, drones, close range high damage etc.
Things I like quite a bit less . . . .
Okay, plus and minus. Plus is that at the beginning of a tactical battle you get to choose where to deploy your mechs in a starting line. That is a good thing. Bad thing is that during this deploy phase you are locked to a camera view which sees all those mechs line up in a column, which means they overlap each other. Fiddly. The actual battle cam can be rotated and the view is just fine.
Run duration. Actually, unsure about this, but if you compare a run of this to say, Monster Train or Slay the Spire, or Roguebook, this probably takes twice as long as those. That said, it may be similar to the likes of Across the Obelisk and Hand of Merlin. Part of the time is what you spend fiddling around with mech parts and upgrades between missions. The actual combats are probably similar to the duration of an elite or boss fight in those other games. Given the combats take a bit longer on average, I am not sure I would ever want to climb Ascension / Calamity / Covenant levels like in those games with shorter combat.
