Just WOW! This game is close to perfection! The puzzles are great, challenging and very logical. A rare feature. Graphics and music are great also. English translation suffers a bit, and item & hotspot descriptions are not always helpful.
A must-play!

The game is worth playing to unravel the mystery of the alien visitation. But I'd advise anyone to have a lot of patience or consult a walkthrough when trying to solve the puzzles.

+ graphics

+ sound

+ atmosphere

+/- good mystery, but the story needed to unfold better.

+/- puzzles (e.g. the water pipe fix makes no sense - round pipe/flat plate?)

- movement (sluggish)

A very competent and engaging game, but there are distracting mistakes and grammar problems in the dialogue. The story feels poorly fleshed out in places, but the grammar may be a contributing factor.

On my first attempt I encountered an early glitch which prevented me from continuing. Players would be advised to give Wilson the Pulse Reader before exploring his dialogue options (or looking at the blast door), otherwise the option to give it to him will be replaced with something else. There is seemingly no way around this once it happens.

The puzzles are logical and enjoyable for the most part, but are not informative enough. Telling the player "I won't touch that" or "Nothing special about it" (paraphrased) when they examine something important doesn't give them enough information, or any idea if they are on the right track. (For example - trying to cut an important-looking cable gives a standard "That won't do anything" without any suggestion that you can cut another identical one nearby.)

There are a lot of good things about this game and I recommend playing it, but it has plenty of glowing praise already. I wanted to point out some of the frustrations I had with it.

Its really a great game, played it like 3 years ago and just remembered of it somehow. But it was really hard to find again. I searched the internet about 2-3 hours, untill I found it again, and just because I remembered that there was something like "infinite" in the game title. I searched for "adventure" "north pole" and such things. and I just saw that there are 2 other games of sector 13 now, have to try them too ;)

Really nice and scary atmosphere.

Very well made, perfect atmosphere and I appreciate good one-click controls.
Only drawback is lack of communication with other characters and sometimes too difficult puzzles.
