Unfortunately, downsides of the game overweight all good things it has.
It might look good at first glance, but the more you play - the more you realise.

Game is trying to implement XCOM style TBT, but does it a wrong way.
At the core here are classic mechanics:
- Turn based movement with covers
- Unit progression and death possibility
- Picking same units consequently has penalties

But that base was heavily modified by two factors:
- There are loot on the map that you can collect in order to buy equipment for your units.
- There is stealth option that is kind of enforced and gives enormous amount of unit progression.

The loot part results in forcing you to move stolen fridge for whole 10 turns which is a lot. It is boring and slows even more gameplay that was already slow without it. It looks good on paper but does not work in reality.

The stealth part here gives benefits of saving units since no one is hurting those, but again, makes game even slower. Also it gives units enough exp to get max level after the very first large mission. It seems like you should just ignore stealth in sake of better gameplay but the game forces you to use stealth by all means - you have limited ammo, your units may die in a shootout, missions may fail when you are spotted or termination timer may start.

So, standard XCOM mechanics does not go well with looting and heavy stealth enforcement, That makes game extremely slow and unbalanced.

The last thing to mention here is a story - it is a complete garbage (still better than stormgate).
You are playing as organised crime group identifying self as a police. When they are not looting everything they see, they are ruining city infrastructure.
Mission briefings there - are some cliche super villain things. Like "I've lost my harmonica by betting it against crime boss - please steal it from his mansion".
You'll probably stop reading that BS after a first few.
