Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Sep 1 → 0.43/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

plz make radiation island 2 or remaster this.
Played this on an iphone when I was 10. The Steam version nails everything. Creative gameplay and interesting story. Though a little repetitive at times/

补票,回不去的何止是时间。
10年前在ios系统上玩过盗版,满满的回忆。现在上船补票,全成就通关。不得不说,十年前的游戏,只有2GB大,剧情玩法仍不输如今各种沙盒类生存游戏。好评!
This is one of the best survival games you will ever play. When I was in high school (2012) I found this game on the apple store and it was so fun I put in the time and beat the entire game. 10+ years later, you wouldnt believe my excitement when I found it had been ported to the steam store. It was an insta buy for me. Radation Island is a traditional survival game, but it is so simple that it makes the game really fun. Theres really no hard grinding, all the items are fairly easy to get, there are no overpowered enemies, and the crafting system is really simple and easy, and the world is so massive you can spend hours to complete the main objective of the game. First: the world. Its absolutely huge, and made up of 4 islands (3 large and one small) in the shape of a radiation symbol. It has beaches, tall mountains, lakes, rivers, and jungles. There are buildings spread out everywhere, from small fishing villages to military complexes. The game features all sorts of weather effects and honestly, they are quite beautiful. The graphics are comparable to something a bit better than original xbox or ps2 games. The game is really forgiving, theres no grinding for stuff, and if you die, you will keep your inventory and occasionally lose what you had equipped. Endgame guns are easy to come by, and gathering items is really easy. Enemies arent very difficult either, they can all be killed in 2 - 3 shots of any medium to high tier ranged weapon. The game has basic status effects which can kill you, such as hunger, viral infections, and cold, but they are all really easy to curb if you are prepared. If you die, you will respawn at your bed with all your stuff. You can place beds in any building throughout the map, and the map is full of them. The game has its own story - its basically the Philadelphia Exoeriment, except the Japanese attempted it on a huge island chain and everything went wrong and everyone has turned into zombies. The game has you follow an objective of turning off massive tesla towers on each island. There are about 5 on each island, and as I said earlier, each island is massive. You have to do a fair bit of walking to get to each one, and its not always a straight walk. There is also teleport points spread throughout the map, and once you discover them you can travel between them with no penalty at all. The crafting system is really simple, there are basic tiers of items, and some are uncraftable but easy to find. The game will never force you to grind or punish you in order to get items. You dont even have to make use of every feature the game has to beat it, which lets players go as deep or shallow into the games mechanics as they want. You can even build structures, but you are perfectly capable of surviving using the pre placed structures. I have to say, playing this game even after 10 years, I still feel the same excitement as I did back in highschool. Its very relaxing compared to other survival games, while still retaining a fair bit of challenge, as well as all the other gameplay mechanics youd expect from a traditional survival game. If you really enjoy survival games, dont miss out on this one. Its cheap, fun, and will give you hours of enjoyment.
It's buggy sometimes but the game itself is pretty fun. Beautiful scenery for such a janky game.
I believe I got this game for dollar or two. This is a bare bones simple first person survival game. However I somehow found myself liking this more than I thought I would. Several others of my family tried it out and had fun with it. Dont expect alot just enjoy it for what it is.
cleared the first and the center islands. Truly a unique experience. It amazes me how this game was initially created for mobile platforms and only some time later ported to pc. This just shows how developers on mobiles cared about their craft, considering that this game was released on devices like iphone 6 and 7, whereas now, having phones that are 30 times more powerful, the only games we see on them are "2d or one click or gacha or all of the above" games
I know this is a beloved indie game, but for me, coming into it in 2026 with no prior expectations or nostalgia, I can't say that I was really enjoying it. I completed the first island and figured the rest would be more of the same, only gradually more difficult, but to me it was simply getting too repetitive and the survival elements too simplistic. Much better survival games have been made since. Not to mention the jankiness of it all (bodies still moving after death, for example). Still, there's a lot of content for your buck, especially if you purchase it on sale, if you still want to check it out for yourself.
