Based on community and third-party reviews of the public repo (as of Q2 2025):

The gaming community has reacted with both euphoria and skepticism.

By mandating that any change to the binary must be reflected in the source code (via the transparency log), the Verus system prevents malicious actors within the development pipeline from injecting hidden backdoors or "master keys" into the released software without code review traces.

Verus uses a light-weight hypervisor (similar to VirtualBox’s raw mode) that sits below the operating system. This component is not fully open source—but its interface is. The verification process ensures that the hypervisor only accepts commands signed by the verified client.

Because the hypervisor is tiny (under 5,000 lines of assembly and C), security experts have verified the binary via formal verification (mathematical proof of correctness). This creates a chain of trust:

If a cheat developer modifies the open-source client to lie about mouse movements, the client’s hash changes. The hypervisor detects the hash mismatch and reports the cheat to the server.

First of all, I want to thank all the players who played the game, provided feedback, endured, shared the joyous moments, kept pushing the game in the right direction.

I want to thank /r/mmorpg for being an open platform for mmorpg enthusiasts, I posted on /r/mmorpg at the end of 2016, and I've been improving and shaping the game with the small early adopter userbase ever since.

I want to thank Mark Jayson Lacandula, aka Json, I started working on the game in June 2016, launched very early around August 2016, he was one of the very first players who tried the game after seeing my tiny Adsense Ad. I didn't take him too seriously when he wanted to try my in-house map editor, but shared it with him anyway. After a very short time, he shared the first map he made, at that moment I knew I discovered a rare natural talent. He made all our maps, learned pixel art, extended our tilesets and sprites and kept exploring, he was and is always there, through the good times and the bad times. Game development is no easy task, contrary to popular belief, it's not rewarding, you rarely reap the benefits, up to this point, we didn't reap, but he never quit - so thank you Json. I hope after Adventure Land, you keep on working in the game industry. (Reader: If you are a talent hunter, do reach out to him) verus anticheat source code verified

I want to thank Ellian, our freelance pixel artist, for being the most professional freelancer I've ever worked with. No one is more reliable than you. Adventure Land started with an off-the-shelf 16x16 icon pack, with Ellian, we created a custom 20x20 iconset, with the community we dreamed, Ellian made. Workload-wise, Adventure Land is a small-fish, but through 2 years, he was always there at a moment's notice. To extend our iconset 5-6 items at a time :) If I could do it all over again, maybe for Adventure Land 2, I'd love to create all the tilesets and sprites from scratch with Ellian.

I want to thank all the developers, artists, composers, whose libraries, assets and work I used in Adventure Land. Based on community and third-party reviews of the

And thank you for reading, and hopefully for playing Adventure Land :)

I want to also thank Steam for being such an awesome platform, 1+ years now, it has been driving new players in, no advertisements or marketing.

Another thanks to Google Cloud for providing us startup credits, it really eased my financial burdens during this development stage. If a cheat developer modifies the open-source client

There's one non-breakable main rule, you can't upset, bully, or sadden other players - Adventure Land thrives on being a positive game with a positive community. When you treat other players with love and respect, they'll treat you that way too!

The secondary rule is to not abuse the game, you can do pretty much everything with Code, and the game, we are even exploring allowing non-UI botting, but, please don't DDOS the game, or intentionally abuse bugs you find. We have lucrative bug bounties

Third rule is to respect the character limits, maintaining the game is beyond imagination costly, almost non-feasable, If everyone respects the limits, we won't be needing to add irritating captchas etc. to keep playing. While you might easily use a VPN or server to play with additional characters, please don't (It has been done in the past, at 2+ accounts, it usually gets noticed fast, you'll only force me to divert my time and energy into battling multiple accounts, please don't)

Selling items, gold etc. with real money is forbidden, don't waste your money, but maybe buy 1-2 cosmetic items to support the game :)

Offensive or insensitive nicknames are forbidden

Breaking the rules usually result in temporary bans, don't be afraid to try new things, as long as you mean well, there won't be any consequences

Have fun

Adventure Land uses Cookies for authentication and settings, cookies are stored between HTTP and HTTPS

Due to popular demand, and technical challenges, game can be played over both HTTP and HTTPS, over HTTP, if you are on a compromised network, your data will be exposed. If you are playing the game from Steam or Mac App Store, the game uses HTTPS by default

Adventure Land uses Google Analytics for statistics

Adventure Land uses Cloudflare for security and filtering, almost all HTTP/S data goes through Cloudflare, so they potentially access every data you provide

Adventure Land uses your location data to determine which game server is broadly closer to you

Adventure Land stores your encrypted password, characters, character names, data you provide, your IP (used extensively for the character limits logic), character actions and there are various logs and backups of these data, there's currently no system to delete these logs and backups, but as cloud storage is extremely expensive, I personally want to start deleting them in the future, but couldn't find the time yet

Adventure Land doesn't have a reliable way to send emails, so it's a players responsibility to keep themselves up-to-date on this privacy policy, but the main theme will never change, Adventure Land is a game with no intention of misusing a players data

I'm an indie developer doing my best to protect my players and meet their needs, but we live in a chaotic world, If you are a regular player reading this, please be careful, while I do everything to protect you and your data (especially more after everything I've experienced since I launched the game, which made me grow more as a developer and a human, at least I hope), nothing is safe on the Internet, always approach things with this fact in mind
