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 Aug 31 → 0/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.

[h1]Achievement Hunters[/h1] You can complete the achievements in under 10 hours if you focus on the game entirely not using the idle functionaltiy at all [i]This review made when I not only 100% all achievements but achieved maxing all Swarm Growth Passive Upgrades & completed all planets & difficulties[/i] [h1]What is This Game?[/h1] A central tower defense game where you have to fend off against waves of enemies, after you earn enough experience, you level up then you can choose a skill, attack style or bonus effects to help you last longer & eventually beat the planets [h1]What to Expect[/h1] [list][*][b]Auto/Idle[/b]: If enabled, it will choose a select option in a session after 4 seconds has elapsed [*][b]Swarm Guard[/b]: 7 different swarms to choose from with a variety of stats & bonuses each comes with, intially locked until you meet the requirements by beating specific planets to gain access to them [*][b]Wave Speed Multiplier[/b]: You have 1x/2x/3x/4x available at the very start [*][b]Skill Abilities[/b]: You will be able to choose 3 immediately, with a 4th afterwards at some point, a 5th can be chosen with a specific Swarm Guard, skill abilities all have a max level of 20 of course each level having it's own stat bonuses with a range of different types of categories & effects [*][b]Swarm Growth[/b]: This is your passive upgrades section at the front main menu which has a variety of upgrades to make you more powerful during your sessions you earn swarm crystals from planets & endless by defeating each enemy & bosses [*][b]Enhancement Chance for Session Selections[/b]: The selections can appear as higher quality giving you more levels for a single option, for example, instead of getting just a level 1 up on a selection, you can get 2 & up to a total of 4 levels, but this requires you to upgrade the options in the Swarm Growth Upgrades Menu to increase the chances which has 3 options of levels from x2/x3/x4 chance upgrades [*][b]Storage[/b]: As far as I'm aware it's infinite [*][b]Planets[/b]: 15 planets total, all planets have a time limit of 20 minutes to survive with increased difficulty for each progressive one, the first 9 planets have a single difficulty, with progressive relic, gems & material increased chances, where relics of Legendary the max can be achieved on the 9th planet, upon reaching the 10th planet onwards, they have up to 3 difficulties with increased rewards as well as from the 10th planet onwards you can earn the best relic quality of Mythic [*][b]Relics[/b]: Comes with stat affixes tied to them, the higher the rarity of the relic the more affixes it can hold up to 5 for mythic red [*][b]Mutation Stat Bonuses[/b]: Allows you to reroll the stats on relics, up to a maximum mutations can be initiated & you 'can' reroll each stat & not locked out after choosing one, which in most games usually only allow you to reroll only one stat not multiples, so that's a plus, the highest rarity of a stat you choose to reroll, will be of that rarity or lower you can choose from [*][b]Presets[/b]: In the relic equip menu, you can select a preset loadout, letting you manage up to a total of 3 presets to quickly switch between the type of builds you can have & easily switch between them at any time in the relic equip menu [*][b]Gems[/b]: Relics can have up to 2 gem slots which gems can then be slotted with various bonus & effects, rarity & stats vary, I suggest to collect them all [*][b]Material[/b]: These are specifically for enhancing relics or mutating relics stats [*][b]Ability Codex[/b]: At the top at the main menu screen will show & tell you about all the abilities you can find in a session, clicking them will give more details of either max count or even scrolling down to review levels of skill abilities [*][b]Bless, Exclude & Skill Refresh[/b]: These affect a session selection of bonuses, Blessing an option gives it a greater chance of appearing more often, Exclude prevents an option from appearing entirely & Skill Refresh allows you to reroll your options entirely, the quantities of these options can be increased in the Swarm Growth Upgrades & Skill Refreshes can also be found on relics [*][b]Potions[/b]: You can find them in a session at the bottom will be some icons & a hotbar where when hovered over state its effect & quantity with a number under that item that you have available to use[/list] [h1]The Bad[/h1] [list][*][b]ENDLESS, It's Not[/b]: Every planet is capped at 20 minutes, endless mode is capped at 60 minutes & there is no auto-restart feature [*][b]Relic Appraisal & Grinding[/b]: You can't sort in the appraising section not by any means, so it makes it a long tedious process if you've got lots of relics to look over [*][b]Auto/Idle Issue[/b]: Blessing/Excluding while the timer reaches 0 will Bless/Exclude that selection then the timer will go into the negatives & never choose an option [*][b]Mouse Hard to See[/b]: Despite specific mouse features with different colors & even outlines, among all the particles on the screen, it's still hard to locate the mouse effectively, making it difficult to navigate the hotbar of potion effects [*][b]No Quick Hotkey for Potion Use[/b]: No easy hotkey for using potions [*][b]Planet 10 Difficulty[/b]: Going from Planet 9 to Planet 10 difficulty scaling, you'll basically hit a wall which will halt progress until you grind a bit to enhance your relics as well as finding mythic relics even if you lose on Planet 10, you can still get drops for mythic rarity [*][b]Mutation Relic Rarity Limitations[/b]: The rarity of the stat you choose to reroll can only be that rarity or lower, never higher [*][b]Auto/Idle No Priority Selection[/b]: While idle works during sessions, the effectiveness is lacking, it doesn't prioritize selecting anything that you have added blessing to nor does it prioritize the ability to get enhanced selections of x2, x3 & x4 level upgrades & can still select single level options [*][b]No Auto Restart a New Run[/b]: After a completion of a session, you must select to continue that returns you to the main menu, if only there was an option to loop planets without stopping, truly idling or in endless as well [*][b]Stimulant, Potion & Fortifier[/b]: This all pertains to the same feature which I found confusing from different sources of the game, which should probably be modified to describe the same function from each of their sources[/last] [h1]My Favorite Build[/h1] [b]Intelligence/Skill Ability[/b]: Swarm Guard Riftfang Nock; +1 projectile to main skill, hits cause small AOE, along with my 3 main relics that all have skill cooldown & skill projectile amounts all of which are all enhanced to the max level of 30, all 4 relics also have the highest damage possible from all 8 gems slotted [b]My Four Favorite Skill Abilities[/b]: [u]Whirling Bone Spike[/u] which is great for close & mid range all around & pierces through all enemies, [u]Mycelium[/u] which is perfect for close range defenses at really fast rates, [u]Cosmic Shockwave[/u] which projectiles are flown across the screen & pierces through all enemies & lastly [u]Spore Puffball[/u] well designed for full screen bombardment which spawns entities around the surrounding area & then they shoot spore projectiles of their own which can seemingly blanket the entire screen if you have enough projectile count, skill cooldown ect.

前期节奏偏慢,到了第六个星球难度上来了,割草感更强了,第八个星球需要考虑遗物、宝石搭配问题。比起幸存者类游戏其实更像增量游戏,不过游戏体验还是很不错的,游戏性能还是很优秀的,三倍速丝滑割草没有卡顿的现象,期待最后的无尽模式
Glad to finally see it released. Having a blast
Für ganz ok befunden 7/10
Cool game just farm the planets go in endless and farm like crazy :D
很棒的幸存者like游戏,怪物和道具种类丰富,特效做得不错。
技能搭配比较丰富,如果嫌麻烦不想研究技能效果,打开自动选择功能,当挂机游戏来玩也可以,技能堆起来以后清怪很舒服。变成小分辨率放在屏幕角落贼爽,上班摸鱼两不误,不过老板走过来不能最小化有点吓人。
Excellent jeu, mais malheureusement la courbe de progression n'est pas bien équilibré... Suffit de 12h si nous sommes actif pour clean l'entierté du jeu. Soit de 20h ( vers moins ) pour clean tout le jeu également en full auto. Suffit d'avoir 3/4 des amélioration a 50% up pour clean tout le jeu, les artéfact sont même pas nécessaire ni même les gemmes pour finir tout le jeu
挺好玩的,比较轻松。还有小窗模式,可以调整倍速+自动选择强化,挂机自动刷。推荐!
Fun, promising mechanics and a fresh take on the survivor-like formula. The mid-to-late game opens into a smooth, satisfying horde-mowing loop—great stress relief. Desktop mode fits perfectly: even with huge enemy counts and the game running at higher speed, it stays smooth.
