So Chains of Freedom - promising game. I would love for Steam to have a maybe button because its not a bad game, especially if you like turn based combat.

Lets break it down :

Game-play : you have a squad that alternates between 2-4 soldiers, turn-based combat , you got AP which is never enough. When in exploration mode you can freely explore the area, when you encounter soldiers/enemies it goes into turn base.

Combat : it's well done but so infuriating at the same time - the AI is good ( flanking , takes cover, trows explosives, retreats etc ) but every fight is usually at least 2-1 - so lets say you got 4 soldiers there will be at least 12 baddies out of which a couple of them will be bullet sponges - ohh and they can call for reinforcements - and you never have enough bullets or AP. Also another strange choice when you start fighting the professional troops - they got overwatch you dont.

Story : Meeh - there is a story there akin to resident evil but i never got into it.

Repeatability : I reckon once you will finish it you wont pick it up again , same soldiers, same maps same action.

Its not a bad game if you like turn base combat because thats literally 90% of the game, but it becomes repetitive fast.
Maybe get it on sale.

Game play is fun but :
I upgraded my tank with extremely rare materials and gave him extra crystal slots which are permanent non refundable 1 time buffs.. and the devs kill off the character in the story without refunding anything. This must be one of the dumbest decisions I've ever seen.
Constant backtracking and no map to see where you've been or where you should go.
The path is blocked by 2 boxes, hip high, in your way... they are military guys and cannot pass 2 boxes.

It could be good, but there is constant limitation and frustration for it's own sake.

Yeah... I don't know.
There's no neutral option, so it's positive.

On one hoof it's pretty nice game at the start. The way how collecting supplies is made, the way how battles are made.
On other hoof... It's not an X-COM (it's not surprising, but if you only knew how much times I've been disappointed in that on other games). It's not a negative thing, just a fact.

So...

Pro: Tactics is here.
♥♥♥: Tactics is not that deep as it could be, it's pretty plain, actually.

Pro: Plot is interesting for some degree.
♥♥♥: All plot-twists are pretty predictable and doesn't surpise at all.

Pro: You have shortcuts almost everywhere to shorten your backtracking.
♥♥♥: You have to backtrack if you want extra supplies or those useless shiny crystals.

Pro: You have a lot of bio crystals to weild.
♥♥♥: You'd probably find 90% of them useless and will use the same set of ones till the end of the game.

Pro: Woah, stealth.
♥♥♥: Stealth is redundant and absolutely unnecessary part of the game, it just made for no other purpose than just being inplemented in game.

Pro: You can craft (for some it's a ♥♥♥, tho)
♥♥♥: You can craft limited set of things, which is selected by... I have no idea how. You can craft medpacks which increase your HP permanenty, but you can't craft armor. You can craft shotgun gauge shots and molotov, but can't craft incinerating shells for your flare (which is technically a shotgun and uses 12 gauge shots, what).

In summary: it's linear plot-driven game with no signs of replayability since characters are the same, they have fixed set of the abilitites and such. Yeah, you have bio crystals, but, eh.
Also, closer to the end of the game it's too much of unnecessary fights for my taste. They become tedious. But it's only in last two chapters or so.

It's fine to play it once, and it's worth to buy it without discount because it's base price is more than adequate for such game.
