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.

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.

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.
♥♥♥♥ this game and it's ♥♥♥♥♥♥ save format.
迟来的测评,好游戏无需多言—非常好玩!
I really like this game! It's very simple, but not blow-over easy. It has great atmosphere that scared me as a kid when I played it on mobile years ago and great atmosphere that scares me now. Awesome experience!
Es un exelente juego para pasar el rato y lo recomiendo mucho, pero tambien estaria bien que agregaran el radiation city ya que lo tengo tambien comprado en mi telefono y me gustaria tambien poder jugarlo en mi pc
[编辑于20260707] 爷青回! 当年抱着pad那是一日又一日,直到后来不知道为什么出bug打不开了 偶然回想起自己最初爱上的开放世界生存制作的游戏,问了D老师,结果真找到了,还正好在打折,太好了!
Radiation Island is an open-world survival adventure developed and published by Atypical Games that transports players into a mysterious alternate reality born from the infamous Philadelphia Experiment. Instead of following a heavily scripted journey, the game encourages players to carve their own path across a sprawling island where abandoned military compounds, forgotten villages, dense forests, frozen mountains, and hazardous wastelands hide both valuable resources and unsettling secrets. The premise immediately establishes an atmosphere of isolation and mystery, giving every expedition a sense of purpose as players search for answers while trying to survive in an unforgiving environment. The game's greatest appeal comes from its emphasis on exploration and self-sufficiency. Every corner of the island offers opportunities to discover useful equipment, hidden bunkers, research facilities, and crafting materials that gradually improve the player's chances of survival. The world feels surprisingly expansive, with diverse landscapes that prevent exploration from becoming repetitive. Whether climbing steep cliffs, crossing lakes, venturing into caves, or scavenging through abandoned structures, the environment constantly rewards curiosity with new resources or unexpected dangers. Survival mechanics are woven naturally into the overall experience. Players must carefully monitor hunger while gathering food through hunting, fishing, and foraging. Collecting wood, ore, herbs, and other materials becomes essential for crafting increasingly advanced equipment, weapons, armor, and supplies. Radiation zones, harsh weather conditions, and environmental hazards force players to prepare before venturing into unknown territory, creating a satisfying balance between risk and reward. The progression system steadily unlocks better tools and stronger gear without overwhelming newcomers, making each improvement feel meaningful. Combat provides enough variety to keep encounters engaging throughout the adventure. Players defend themselves against aggressive wildlife including wolves, bears, crocodiles, and mountain lions, while abandoned facilities introduce dangerous undead enemies guarding valuable loot. The gradual transition from primitive weapons to bows and firearms delivers a rewarding sense of advancement. While enemy behavior occasionally lacks sophistication and some encounters can become repetitive during longer sessions, resource scarcity ensures that combat remains tense, encouraging players to think carefully before wasting ammunition or engaging unnecessary fights. The game's atmosphere deserves particular praise for successfully blending survival with science fiction and subtle horror. The mysterious alternate dimension is filled with strange anomalies, abandoned experiments, and remnants of civilization that hint at a much larger story without relying on excessive exposition. The day-and-night cycle significantly influences gameplay, as darkness increases tension and visibility becomes limited. Combined with dynamic weather effects and immersive environmental audio, the island often feels genuinely lonely and unpredictable, encouraging cautious exploration rather than reckless wandering. Considering its origins, Radiation Island presents an attractive world with impressive environmental variety. Forests, beaches, snowy peaks, rivers, and underwater locations each possess their own visual identity, helping maintain a sense of discovery throughout the campaign. Water reflections, changing weather, and expansive draw distances contribute to the immersion, even if some character models, animations, and textures reveal the game's age. The visual presentation remains more than capable of supporting the adventurous tone the developers aimed to create. One of the game's strongest qualities is the freedom it grants players. Objectives rarely dictate exactly how progression should unfold, allowing experimentation with exploration, crafting, and survival strategies. Some players may spend hours building equipment and gathering resources before advancing the main objective, while others may focus on uncovering hidden locations and story elements. This flexibility gives Radiation Island considerable replay value, as different playstyles naturally lead to different experiences across the island. The experience is not without shortcomings. Inventory management occasionally feels cumbersome, enemy AI can appear simplistic, and some gameplay systems lack the refinement found in more modern survival titles. Certain mechanics also reflect the game's mobile roots, making a few interactions feel less polished than those in contemporary PC releases. However, these flaws are generally outweighed by the game's enjoyable exploration, satisfying crafting system, and consistently engaging survival loop. Radiation Island successfully combines open-world exploration, crafting, survival mechanics, and mystery into an entertaining adventure that remains enjoyable years after its original release. Its emphasis on freedom, environmental storytelling, and gradual progression creates an experience that rewards patience, preparation, and curiosity. Although it may not match the technical sophistication of larger-budget survival games, it delivers a memorable journey through a fascinating alternate world filled with danger, discovery, and adventure. Fans of exploration-driven survival games will likely find plenty to appreciate in its expansive world and rewarding gameplay systems. Rating: 8/10
