A nifty little game, about 4 hours of content to maybe 6 if you linger about to find spots of intrigue. Liked how interactive the various systems in thew sub where, though wished there was a few extra, for the low price, i felt like it provided enough. But, i did encounter some crashes when messing around with shooting out an absurd amount of flares at once, and with trying to leave a trail of beacons to follow back, easy enoguh to avoid by just clearing beacons for each area, and not spamming flares whilst docked. The ending i found was alright, though there might be an alternative one to discover, really wished i'd seen more than the 2 or 3 spooky things on my screens though, but adored the camera's in general being a live feed for once. pluss, the sub control felt pretty smooth and nice too, specially the docking. ^.=.^4 found this helpful
Do you like feeling claustrophobic? Do you enjoy the creaking of your only shelter fathoms deep in oceans? Do you just wanna enjoy music in the dark? Look No Further; Dark Sea. Between navigating the endless darkness and my own mind making every shadow and noise a monster, I've had a lot of thinking to do and I've come to a conclusion. I will be staying topside for the rest of my life.1 found this helpful
Started game, briefly read manual, died of asphyxiation. Started game again, read manual extensive. Died laughing and relishing at the fact that this submersible is not only using a diesel engine actively but also it is the stalinium made V-2. Now more seriously its a great game for a respectable price, the mechanics of the sub are nice, it controls like a metal tube in water and the atmosphere is sweet. ALSO THE COUNCIL HAS DECIDED THE SQUEEZE FOR ALL!!!!1 found this helpful
While clearly similar to Iron Lung, Dark Sea is extremely under appreciated. Anyone who enjoyed Dark Lung owes it to themselves to play Dark Sea. It's 4 times as long, has some actual puzzle elements, and is a much more immersive experience overall. For its current price, there is truly no reason not to give this experience a try.
Love it.
yikes, do not buy I got ripped off.. this is so bad $7
