Thank goodness you're here. Someone's caused a mess in the lab, and viruses and bacteria are running amok! Take control of the body’s defenses and protect the precious stem cell from the hordes. There's clearly something very ominous going on here, and we need to get to the bottom of it! Antidote is an exciting strategy game inspired by science, which means it’s full of fresh new ideas. With 13 unique defenses at your control and lots of different ways to play, we guarantee you've never played anything like it before. It's easy to get started, but only the smartest and strongest will be able to defeat the final boss. We know the subject area is a bit... icky... so we covered most of the slime with adorable characters and beautiful, challenging levels. Blame us if your friends get fed up of hearing how cute Cholera is...! What's all this about science? You've probably played games before that have inspired you and left you with a new passion, and even some real knowledge. Building space rockets, exploring history, being bread... they're all great. That's what we aim to provide with Antidote. You don't need to know anything about science to play and beat the game, but we guarantee that afterwards, you'll know more about it. Free to play? Where's the catch! Antidote is free to download and play, with a single in app purchase that lets you play as much as you want, whenever you want. We've got exciting new features coming, but we'll never take anything away from you. Oh, yeah, we don't like adverts ruining our games, so if you want to see adverts, this isn't the game for you... Sorry! ## Key features - 13 unique defenses - Science-inspired strategy - Challenging levels - Adorable characters - Unlock lab mystery - Learn about science ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Infinite Charge | $2.99 | one-time | | Maximum Protein Generation | $2.99 | one-time | | Protein Shipment | $1.99 | one-time | | Protein Shipment | $4.99 | one-time | | Protein Shipment | $8.99 | one-time | ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/antidote/id1157446651/reviews.md ### 3/5 — Ingasicasitasivalienta *2022-05-28* 不想做自己想做一些力所能及时的事情吧、一切也可以慢慢变成这样说我觉得真的是一个人都 ### 5/5 — Impossible (not really) *2022-01-11* Level 9 is impossible make it easier please (PS sorry for harsh review I figured it out now lol) but still make it easier it’s super difficult **Developer response:** Hi bunny bunner! Thank you for your awesome review! ✨ In level 9 I would suggest making a long, narrow route from white cells through the map so the enemies take longer to reach the stem cell. Placing them and mileys is the key, hope you'll manage to beat the level! Happy microworld exploring and stay safe! 🔬😊 Cheers, Emma from Psyon Games ### 4/5 — Fun game *2019-08-14* I love the idea of the game. It starts of easy with very good science. It guides you and helps you with game play. And then you get to level 16 and it is insanely hard. I can’t get passed it. **Developer response:** Hi Rivkahcarmel! Thank you so much for your feedback! We continually optimize the difficulty and there are big changes coming soon to it. But for now, I would recommend to get vaccinated (in-game at least) and try to build 3 Mileys at the beginning of the level. After that try to build more Mileys between waves. And of course, make the maze long as possible. Happy microworld exploring! 🔬😊- Niko from Psyon Games ### 3/5 — I have to admit *2019-05-12* This game is so fun but goes so fast the charges are annoying I mean you could win an extra charger every time you beat a boss that would make it more fun edit so I bought the unlimited charges but what’s it worth this game is so hard and so frustrating I could scream it’s like I spent almost three hours trying to beat level 8 and I got it and the tutorial said we would upgrade the towers soon the tower upgrade is needed to be added in level 9 it is way to hard I just can’t take it something needs to be changed please give a response when you fixed this problem Edit okay to be more specific the towers need to be upgraded sooner and make the game easier it’s too hard that’s pretty much all I have to say about this game if I have anything else I will edit this again Edit I kept my promise okay this game again is very hard I mean it’s so hard if you buy the unlimited charges it’s no use use you just wasted your money beacause this game is so hard you literally can not beat the game it’s so hard please fix this happy new year 🎈 are the developers ever going to respond I don’t know but you know it’s one thing to not respond but to make your costumers angry is one thing I have been waiting for a response for a couple months now I would tell everybody how bad and hard this game is for one thing and the developers do not even give time to read they reviews Okay it’s been how many months now and well they made a new update but did they make the games easier I don’t know but I sure hope they did **Developer response:** Hey RaBV!
