About
The Message from Deep Space is an odyssey of puzzles. Take the role of the mission's Translator, working alongside a scrappy band of scientists, and venture headfirst into the world of deciphering an alien language --- completely from the ground up.
Set in 1973, Earth is the recipient of a meteorite that broadcasts radio waves. In the role of the mission's Translator, the player is responsible for designing responses to the meteorite's transmissions, which, if correct, will elicit new messages from the meteorite. Only through this radio wave dialogue will patterns, words, syntax, and meaning all take form, leaving but one question:
What is it the aliens want to say?
Translate an alien language
Learn about an alien civilization
Interface with a retro computer
Manage a user-driven dictionary
Design radio transmissions by frequency
Collaborate with scientists that respond to your actions
+1000 in-game dialogues
+30 minutes OST
+30 hours of gameplay
Inspired by The Golden Record aboard the Voyager I space probe, The Message from Deep Space takes a realistic approach to deciphering an interstellar message. Beginning with the limited universal constants available to technologically advanced civilizations, the message spans a range of real-world fields of math & science. Decoding the message is tough, but with the support of the game's meticulous linguist, the single-minded computer programmer, and the affable astronomer, it is a challenge fit for anyone with Curiosity and Perseverance.

Minor spoilers, I suppose, for the earliest part of what appears to be a very long game. I have a complaint. The aliens are giving us counts of objects - frequencies of radio signals. The aliens are also said to be sending us transmissions in base 8. You cannot send a quantity of things in a base. You can only *count* things in a base. If the aliens sent us 6 pulses, that's 6 pulses - whether you record it as 0110, 6, 0x06, or VI. But these aliens do a weird decimal-octal hybrid: when counting something, they skip the 8th and 9th elements. As far as they're concerned, the difference between 1007 (decimal) and 1010 (decimal) is 1, not 3. Again, that's how base 8 works, but this is absolute moonshine when you're talking about physical objects: x x x x x x x x x is 9 'x's in base 10, but it's 11 in base 8, but that doesn't change the countable number of x's in the line. What's more, they didn't need the base 8. With 975+ puzzles in the library, they didn't need to stretch out the beginning with base-8 numbers. They could've gone right to base 10 without losing anything. Instead, the integrity of the whole system is undermined by this poorly-executed handwave.

Vous avez quelques restes de physique et SVT, pas trop de problèmes avec la langue de Shakespeare et quelques heures devant vous ? J'ai une bonne nouvelle.
Sort of halfway between a puzzle game and a visual novel. The characters are fun and the puzzles are unique and interesting, though every once in a while there's one that requires you to make a huge and very specific leap of logic that you might just have to look up.
有几个瞬间足以让我感到震撼,像是亲手在字典中填下life、love、hope几个词的时候,又像是在transmission975不知道该输入什么,苦笑着打下 [spoiler] human noun_partition alien love verb_partition [/spoiler] 后,突然听到绿灯亮起的时候。我想这些瞬间冲淡了很多和出题者对不上电波,或者是查阅reference时发现没有自己需要的信息时的气恼,让这部作品为我留下的更多是感动。 这当然是个虚构作品,和“外星人”的交流当然也只是和游戏作者的交流。但借着这些交流,我也在漫长的翻译时光中慢慢思考着哪些东西是universal的,哪些又独属于人类这个物种。先是数,再是质子、中子和电子,之后到生命,最后有了感受、希望与爱。 我很喜欢这部游戏,虽然没有中文,但其实gameplay的部分都用拼音搞定也是一样的,最多是看不懂同事对话而已,需要对电波的部分,网上也有很多攻略可以参阅。 参考游玩时间:25h
Brilliant. Thrills down my skin when I read a comprehensible message for the first time! The goal is simple but so satisfying to attain: communication, learn about another lifeform. It sounds like a game made for science geeks but ultimately, it manages play on your emotions as well at times as you progress with your understanding of their language. Each time I understood the meaning of a new signal, the feeling of satisfaction drew a smile on my face. It's the kind of game you say you'd play 30minutes, but you look at the clock and it's been hours. A real gem :)

Quel jeu ! Une idée très ambitieuse, exécutée quasiment à la perfection, ça donne un classique qui restera une référence pour des années et des années. C'est bien foutu, bien dosé, bien écrit, émouvant, passionnant. J'ai versé ma larme à la fin. Le jeu peut faire peur au début si on n'est pas fan de maths, mais je vous jure que ça vaut le coup de persévérer. Le jeu a tellement à offrir.
50h 一周目通关,一段不可思议的旅程。 再见了沉星之序,你不会是今年的最佳解谜。
J'ai 10 heures de jeu dessus et je sais que je n'ai qu'effleuré la surface de The Message from Deep Space. Un jeu de logique qui m'a reconcilié avec les mathématiques, la physique et la chimie. Un puzzle game extraordinaire, et d'une profondeur qu'on imagine pas.
