Not going to lie, the name “Keplerth” was both intriguing and ultimately accurate.

Keplerth is a top-down survival crafting game reminiscent of Terraria, with art assets straight stolen from RimWorld. Other reviews mention this as being a post-apocalypse knock-off of Necesse, if you know of that one. You will punch trees, create crafting benches, craft gear, and then tackle bosses to unlock the next tier of equipment, resources, and mobs. Rinse and repeat.

There are some interesting innovations to the formula though. For example, there is no XP here. Instead, you unlock new genes based on special resources that drop from basically everything in the game, e.g. plants, mobs, minerals, etc. The genes start simple, with stuff like +5% Evasion or +10% Attack Speed. Towards the beginning of the game, you have plenty of room to “equip” every gene you unlock; later on, you have to choose amongst them and their potential synergies.

I also appreciated how equipment bonuses work. Essentially, each piece of gear has a random set bonus and a random set bonus score (+0 through +3). So, the leg armor you craft might have bonuses to +Defense or +Pet Attack instead of the +Melee you were looking for. And even if it does have +Melee, the final set bonus may only trigger when you have 7/7 equipped and the piece you rolled grants +0. While random can be frustrating sometimes, many survival games are kind of rote in that Iron armor is Iron armor, and thus you only need 22 Iron ingots total to kit yourself out on that tier. This at least means you need to collect a buffer amount of resources. Later on, you get the ability to spend other resources to “reroll” the tier bonuses, so it is not too frustrating for long.

Where Keplerth struggles is… kinda everywhere else.

A lot of the mechanics feel half-baked. One of the early tutorial quests involves you attracting other survivors to your base with a communications tower. What the game doesn’t tell you is that the survivors… don’t really do anything. There is an entire elaborate construction station to create fancy furniture, but ultimately the survivors need 1 (one) recreation item (hot tub) and their heart meter will eventually fill and you click on them for money. That’s it. They do not defend your base, work the fields, or anything. You can also have farm animals like cows, chicken, horses, etc, and they will reproduce asexually as soon as their food meter hits 100%. Cooked food does require a variety of meat and plants for pretty useful buffs, so there is a point to all this, but it doesn’t always make that much sense. Like why have Horse Meat in the game when eggs are really the limiting factor for advanced food?

The special material mechanic I praised earlier is also a bit uneven. A lot of it felt natural at the time, as you just pick up all the things and new stuff seemed to unlock every 5 minutes or so. Eventually though, once your gene grid fills up and you start needing to examine what’s left, you start to realize that 5-6 of the missing genes require Thorns or Apples or some early-game stuff. Luckily the grind isn’t too bad since you can chop most everything down and replant it near your base to more quickly get additional chances when harvesting it – as opposed to having to wander around for more natural-occurring spawns – but the amount of things tagged to Thorns specifically is a bit odd.

What kind of broke the game for me though was one of the mid-tier boss drop weapons. Up to that point, you may have some melee weapons, bow and arrows, some early guns, and so on. Even with guns, there were some trade-offs with damage versus shooting speed. Then you get a 100% drop of an energy beam gun that deals constant damage with zero ammo. While it technically is out-classed in DPS later on, the utility of being able to trigger knockback, certain genes (“each hit adds X effect”), and the lack of ammo makes everything else feel dumb to use in comparison.

Later bosses also get into SHMUP/bullet-hell territory, which forces you to turtle up with your genes and equipment, which makes the fight last ages because you are no longer specced for damage.

Having said all that, I did end up playing the game for ~25 hours or so, somewhat obsessively. Keplerth definitely hit a stride for me after about the 2nd boss, once you unlocked the ability to tame battle pets, get some better weapons, better genes, and start finding other human settlements to spend money at. It is unfortunate how that petered out in the endgame, but what else can you do?

Play something else, I guess.
