About
This DLC follows the ending where Jan Scientist stays on the planet. Average playtime is estimated at 20 hours.
Jan Scientist can finally pursue his true calling. While other Jans left, he stayed to lead a team of new specialists - assembled by and from himself. Only a scientific crew of perfectly aligned altered Jan Scientists can offer the expertise needed to unravel the Oasis phenomenon.
Studying nature's survival here in space is a life-defining opportunity. However, this goal-oriented plan of the Jan Scientists might not be so apparent to Jan Geologist, Biologist, Chemist, or Physicist.
The Oasis, a lush paradise that shouldn't exist, becomes the mystery you will obsessively try to solve.
Terraforming the nine arenas unlocks it, forcing the landscape to yield answers. But with each seemingly right step on a research path, the planet responds with implacable earthquakes and radiation, hinting at secrets best left undiscovered.
Your biggest hurdle? Years-long planetary cycles of scorching sunrises that force you underground. Setting a functional underground base requires building in varied soils, constructing new components, and researching modules like the Cryosleep Chamber, which buys time to witness your scientific actions' long-term effects.
Still, even in cryo-slumber, increasingly vicious cycles wear down your crew’s readiness to work.
Each planetary cooldown offers a brief window to freely explore a dramatically changed surface.
Terraformed landscape opens new building possibilities, spawns bonus-providing pickables, and lets you evolve your research-essential technology by extracting and refining new planetary resources. Specialised structures further let you transform, combine, and amplify what you gather.
Field Labs introduce new assignments for alters to continue their work while you cryosleep. But will they change once faced with the vulnerability of ageing?

Honestly i think it's a solid DLC. it's 12 quid for anouther 20 hours of game play, while also adding completely new mechanics the DLC completely changes the style of gameplay and yet still makes it feel close enough that your still getting the alters style gamepaly i have a note or 2 about the story but nothing that ruins it.
I'm a little sad we didn't see any more of Jan Builder but ♥♥♥♥♥♥♥♥♥ that was a good story. It's a little buggy and it is the number one chuggiest game in my library
总体还可以,水平发挥稳定,如果你喜欢本体的话,建议购入。 原本的资源管理玩法水平发挥稳定,新加的管道玩法感觉也没有雷区(但是我自动化的游戏玩的不太多,可能有误差)。 剧情发挥稳定,如果你觉得本体剧情没问题,那么dlc的剧情也没问题。 唯一的雷区可能是,地图没有像本体一样一直换,采取了一张地图然后延伸的形式。由于这个游戏箱庭的特点,可能地图没有那么丰富,但是感觉还是够玩的
Currently a bug with the biologist where you cant complete his side task and therefor cannot assign him to a field lab.
优化太差,加上幽灵配方BUG吃掉400仓储,越玩越气 11bit老婆出轨孩子打掉之后依旧自动扣钱给抚养费这块
Perfect addition to original game, awesome to spend weekend on going through.
*Chefs Kiss*. If you loved the base content, you will love this. Great gameplay, and one banger of a story line. Mind blown.
If you liked the base game, you'll probably like this. But for me, by the end I kind of didn't care what happened and just wanted to get it over with. The decrease in performance also didn't help. Nice voice acting by Joe Biden, though. Knowing what I know now, would I still but it? Not sure.
DLC is weaker than original in every respect. Feels like a sequel with a lot of potential, but 80% of story, mechanics, and content cut. Every moment feels like downgraded, downplayed, or simplified version of what it would be in the original Alters. Still quite a fun game, just not as marvelous.
This DLC was truly amazing and I would highly recommend it if you like the original Alters. Some cool new Alters, an amazing story and a [spoiler] of an ending (in a good way!) It also picks up pretty much where the original left off so it doesn't feel like those games/DLCs where you are pushed back in terms of tech just to do it all over again. It always felt like you were against the clock (like the original) without really pushing you over the edge. My only real complaint is that you can't really replay it, once you are done with the story it's pretty much over. Still, for the price it is well worth it! I see a lot of complaints about the pipe system, but for me personally it provided an interesting challenge and some nice content for the late game trying to optimize the flow of materials.
