So why did I think of this? Hey, I had fun with it but that won't help you so let's go with the extensive answer.
What's an RPG?
You control a single character, there's no primary stat and there's no visible character sheet. Your equipment is composed of some weapon slots, one consumable slot and some generic accessory slots. Enemies only give meat when you kill them, and meat is actually money rather than XP, but tapes that are limited and you'll need to find definitely act as XP points to spend in practice. Finally the game features a nuanced turn-based combat system with detailed combat stats and what's more or less a campaign through actual « dungeons » (sometimes outdoor).
Make what you want of that.
About the presentation
This is actually relevant as my opinion is that overall the game looks super cool and you might not agree with that. That's not evident when looking at a screenshot from the beginning of the game for sure, but I really like all the unique and detailed exploration screens and by the end of the game all the enemies are two screen tall. They're not all unique and they're variations on similar ones but they're still plenty of cool designs, the bosses generally look super cool and of course all those organs to reveal and eject out of their bodies make them all the more cool.
The overall presentation, metal music, over-the-top heayv metal post-apo atmosphere, mutant enemies, all the, uninteractive, dialogs consisting in the character and whoever he's talking to insulting each other and the plot consisting in the character looking for gas are half of the charm of the game as far as I'm concerned, the game is one of the games with the most cool vibe I've played and if they don't appeal to you then I'm not sure you'll enjoy the game regardless of gameplay considerations.
The walking and the equipment
You'll get to explore a few successive big dungeons. They're midly open, you can explore a bit but will have to explore the key locations with bosses in a given order.
Unfortunately environments are not super interactive. However they're tons of items hidden out of sight, typically behind pillars or just above a wall. They're mundane items, ammo, bombs, buff and healing items, all you will be able to buy at will at some point but some of them you can't buy yet when you find them, which is an alright compromise so that they don't feel like too boring finds yet you won't feel the need to hoard them. A few strong weapons are also hidden, I missed at least one that I can see but don't own the needed key while I also found a super satisfying one this way.
The roster of items is reasonable but all the items are named and come with a cool visual. They're some basic healing items, some bombs of various kind as well as quite some unique accessories providing various passives. Finally you can either buy or find about 20, all unique weapons in total. They're 3 types of ammo and the amount of consumable of each type you can carry is limited. I really like the visuals of the weapons and accessories.
Turn-based dismembering
You'll spend a good part of the game fighting. The game uses an original and well thought battle system. During your turn you've got a few action points that you'll generally spend targetting various parts of your opponent's body. The different weapons can damage a few particular different patterns. Piercing the flesh will reveal organs which will get ejected from the enemy as soon as they're completely revealed. Destroying the right organs will disable the damage, aiming or dodging stat of the enemy but more important than that it is particularly thrilling.
You'll get to equip several weapons as you advance through the game and you will only be able to buy and upgrade a few weapons to the max during the game, which is great as it means the choices of weapons are real definitive choices. Between the type of ammo, and you probably want more or less one weapon for each type of ammo by the end, the different patterns and some really relevant additionnal effects such as armor piercing the weapons feel different and unique. Choosing which one upgrading as you play is fun too, and their rise in power as you upgrade them is real, even the knife will be an interesting weapon which can make an enemy bleed to death if you upgrade it to the max.
If you find most tapes then by the end of the game you'll be able to unlock most character upgrades but during the game you will still choose between different upgrades. They include basic stat upgrades, various big bonuses in the first turn if you won initiative and various ones if you lost initiative as well as upgrades linked with your adrenaline bar which can be spent for special bonuses such as an extra action point or healing yourself.
Many accessories are very unique too.
I think the difficulty will highly depend on how you play and the game will adapt well to different playstyles. I really took my sweet time, run unto most enemies while you can often avoid them. Because I did then I needed to get back and fourth to previous checkpoints to get back to town to refill my ammo quite a bit, earning some extra money in the process. Killing many enemies of a kind gives you extra bonuses so I gained that too. I also spent a substantial time trying not to miss too many things in the corners. Playing this way the bosses were not much of a threat as a result.
However the thing is that you'll find plenty of things when exploring including both types of money/XP and ammo so if you prefer to try to move forward and actively try to avoid enemies instead then I think you'll get a fair but challenging game which is certainly built to allow to play this way. If anything if you don't feel the need to run into all enemies like I do then the game will only be more fun for that, as the game is rather built this way with plenty of enemies but which can generally be avoided, I could say I faced more enemies that I would like but it was only my own fault. Enemies slowly respawn.
I took a note that there's a fast combat option at some point so I'll mention that.
In the end it's a quite unique game carried by a well rendered over-the-top heavy metal atmosphere and an original battle system about dismembering big weird mutants in turn-based mode that I had fun playing. I think that if you're intrigued by both aspects then it's worth checking at least. A demo's available so you can try the game for free.
