Played this for a while, and while I think the core of the gameplay - the combat and going through mech upgrades - is good, it's really the only thing the game has.
The missions are a game design disaster of the highest order.
Some bland small square map with random, but irrelevant terrain.
On which structures are placed almost entirely at random with no logic or world design in mind whatsoever.
On which enemies spawn at random positions with no logic or mission design in mind whatsoever.
There are different mission types, but they are all the same and play the same anyway.
Sometimes, there is a timer so you can't kill all the shit, only what your objective is.
The mission descriptions try to tell you some story, but none of that translates to the actual game at all.
Your lance's AI is... lacking, to say the least. The only commands you can give is "attack that target", "come to me" or "stay here".
The enemy AI is made to focus you - the player mech - down, which generally leads to your useless lance mates being in near mint condition, while you get to soak up all the damage.
Everything feels bland and pointless.
Your only motivation to play is to upgrade your mech/get a better mech. Which did actually motivate me enough for a while, but even that wears out.
tl;dr: What a waste of a good combat/mech system.
However, if you got friends to play this with, do it! I'd say it's actually worth it for that.
