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?

Wymęczył mnie ten dodatek, ale po ukończeniu czuję satysfakcje, dlatego oceniam pozytywnie. Największe minusy dla mnie to: - Nierówny balans, ciężko na początku, zbyt łatwo od połowy. - Irytująca zabawa rurami. Jednak jako całość, to dobre DLC, z zaskakującym finałem. Podobało mi się :)
Oh mon dieu! Oh mon dieu! Oh mon dieu! Oh mon dieu!....Oh mon dieu! Ce dlc est un cocktail de ce que j'adore! Des variables ! Des concepts métaphysiques! Des variables! Des portraits différents de savants avec pour chacun une vision différente du savoir! Des variables! DES VARIABLEES Oui désolé j'overeact un peu ! Mais premier degrés j'ai surkiffé ce dlc, j'ai adoré les personnages qui l'incarnent, c'était un réel plaisir d'aller jusqu'au bout. Le seul bémol c'est la partie "construction", avec les pipelines et tout...C'était parfois assez laborieux, surtout que plus vous avancez dans l'aventure plus le jeu vous incite a optimiser, ce qui peut vous amener a vous battre contre le moteur du jeu. Mais a part, j'ai surkiffé incarner Jan scientifique, c'était l'alter que je trouvais le plus intéressant dans le jeu de base, je suis super content qu'il ait eu droit a un peu d'amour ! DES VARIABLEEEES \(^o^)/
I've played through about a third or half of this DLC so far (I think), and it has been amazing so far. The new characters are fun, the story feels engaging and the new pipes are fun to play with, tho it can feel tedious to get used to them at the start. The only negative, but a kind of funny one, is that I've encountered multiple grammar errors in the subtitles and dialogue selection. I recommend grabbing it, especially when it offers so much for such a low price.
Super !!!
When not crashing it's very good
Dobre, choć nie tak wybitne jak podstawowa wersja gry. Błędy tez nadal nie naprawione - losowe spadki klatek i lagi, budowanie potrafi sie strasznie zgliczować, a anomalie utknąć w ścianach, blokując mozliwość budowy. Mimo wszystko polecam :)
Отличное дополнение к отличной игре. История интересная, несколько раз нагнала саспенса, геймплейно не хуже оригинала. Взял без скидки — не разочаровался нисколько По концовкам мнение с микроспойлером: [spoiler]Оба финала грустные, но только хороший — это настоящее «быть лучше». Он завершает историю Учёного несовершенством, неким ваби-саби. Жаль, что у Яна так и не было времени насладиться спокойной жизнью в Оазисе, как у коллег из Полевых лабораторий, но... в конечном итоге ему — и вам — решать, чем был Оазис и вся жизнь: кругом ада с бесконечными муками или идиллическим раем, который он не замечал за своими стремлениями. [/spoiler]
無限のエネルギーだ!! 計算式確認ヨシ! 前方後方上下左右確認ヨシ!スイッチオン!! ふぁあああああああああヤンbotてんめぇ~~~~!!!!!!!
不管是玩法操作还是指引还是bug完全都不足以给好评的程度,完全就是为了剧情就摁着头玩。身为科学家的分身们实际也没比本体的那些省心到哪去,科学家杨无论在哪都摆脱不了当爹又当妈的职责 。[spoiler] 但是打完结局和跟扬一样和解了,[/spoiler] DLC的主旨是对科学的意义的探究,这点其实不管对话还是文本都铺垫不少了,[spoiler] 一些早期的对话就暗示玩家可能存在"轮回",[/spoiler]但在故事发展方面一些逻辑设定实际都是说不过去的,不过主旨多少传达到了。[spoiler]但是既然前面有300多次的轮回,扬都选择了创造继任者,所以最终变量其实是玩家吗(。不管怎么样我们必须想象科学家扬们是幸福的![/spoiler]
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.
