EndlessDungeon.Game – EuroDNS customer – (United States)
Creators and developers use .Game domains to share interactive experiences across genres and playstyles. Browser-based multiplayer hub Gig.Game expands with AI-driven trivia, bingo, and engagement tools. Epic role-playing game Divinity.Game offers immersive storytelling from acclaimed developer Larian Studios. Award-winning puzzle reinvention TetrisEffect.Game introduces music-driven gameplay and multiplayer expansion. Today, we’ll introduce you to a tactical action roguelite set in the ENDLESS Universe: EndlessDungeon.Game.
EndlessDungeon.Game is the online home of ENDLESS Dungeon, a roguelite action game developed by AMPLITUDE Studios and published by SEGA. The roguelite genre involves repeated runs where players begin again after being defeated while retaining upgrades or unlocks that help them advance further. The game combines elements of top-down shooting, tower defense, and resource management inside an abandoned space station within the broader ENDLESS Universe. Players escort a fragile Crystal Bot through shifting districts, defend it from waves of enemies, and attempt to reach the station’s Core. ENDLESS Dungeon released on October 19, 2023, and is available on PC, PlayStation, and Xbox platforms. Reviews from outlets such as entertainment media website IGN describe it as a fast-paced, tactical experience that blends decision-making with action-heavy combat.1
The game centers on repeatable “runs,” where players open doors, gather resources, build generators, and place turrets to create pathways through the station. Each run offers a choice of districts, with ten areas available across the game. As players collect district keys, they unlock new routes, characters, and story moments that contribute to the game’s progression. Reviews note that the shift from the earlier Dungeon of the Endless’s turn-based strategy to real-time action reflects a deliberate design choice, while retaining the principles of risk management, room-by-room advancement, and planning defensive choke points. Enemy types, environmental hazards, and district-specific challenges shape each attempt to reach the Core.
Players recruit a roster of heroes—each with their own narrative background, abilities, and preferred combat style—to form a team tailored to their approach. Characters can be built toward roles such as damage, zoning, support, or tanking, though the game allows flexible playstyles regardless of role archetype. The station can be explored solo or in three-player co-op, allowing teams to coordinate turret placement, district choices, and wave defense. After each run, players return to the Saloon, a central hub where they can upgrade weapons, enhance characters, interact with NPCs, and unlock modifiers that adjust difficulty or add new mechanics. Critics highlight the game’s environmental storytelling, variety across districts, and the developers’ ongoing refinements informed by community feedback.
EndlessDungeon.Game uses a .Game domain name that matches its focus as a gaming project. The website organizes information about the game’s world, characters, and gameplay features, and it includes materials such as trailers, edition details, and purchase links. The direct connection between the title and the domain name can help visitors easily associate the website with the game. You can learn more by following the game on X/Twitter and by visiting EndlessDungeon.Game.

Forward‑thinking developers use .xyz domains to advance innovation in AI. Ethereum Layer-2 network Ten.xyz is designed to bring encrypted computation and AI agents to web3. AI data infrastructure Hub.xyz builds a distributed network for real-time machine intelligence. AI platform Side.xyz introduces AI-Agent-Marketing infrastructure to support sustainable community growth in web3. In this week’s #AIMonday, we’ll introduce you to an AI blockchain infrastructure designed to help builders create specialized models with verifiable data: OpenLedger.xyz.
OpenLedger.xyz is the online home of OpenLedger, an AI blockchain infrastructure designed to support the training and deployment of specialized models using community owned datasets called Datanets. The platform records actions such as data uploads, model training, rewards, and governance activity on chain to create transparent attribution and traceability. Users can create Datanets, contribute data, and publish models through tokenized mechanisms that document how each contribution influences model development. In July 2024, OpenLedger announced an $8M seed round led by Polychain Capital and Borderless Capital.1
In July 2025 at Pragma Cannes 2025, an ETHGlobal summit designed for founders and builders to discuss the future of web3, co-founder Ram Kumar presented OpenLedger’s blockchain-based protocol for building specialized AI models. He outlined how the protocol is geared toward addressing limitations of generalized large language models by allowing users to contribute domain-specific datasets, fine-tune models through a no-code interface, and receive on-chain attribution for their contributions. Ram described OpenLedger’s focus on data ownership, auditability, and verifiability, and contrasted its decentralized approach with centralized model-hosting platforms. He also highlighted early ecosystem components, including model marketplaces, agent frameworks, stablecoin-based micropayments, and a DEX for model tokenization, noting that over one million users have participated in the testnet ahead of mainnet launch.2
The platform presents itself as an infrastructure layer for the data lifecycle in AI. Its materials describe a system designed to address data quality, attribution, and verification, which the organization identifies as a bottleneck in training domain-specific models. The documentation states that OpenLedger supports specialized data collection through Datanets, each focused on text, image, or audio contributions with format validation. The platform also outlines a Proof of Attribution pipeline aimed at linking training data to model outputs so that contributors can be credited for the value of their submissions. This structure places OpenLedger alongside a broader field of projects that use blockchain mechanisms to coordinate data, model training, and AI agent behavior.
According to LinkedIn, Co-founder and CEO Ram Kumar has experience managing multi-billion dollar enterprise accounts and has worked with organizations such as Walmart, Sony, GSK, and the LA Times. He describes OpenLedger as a decentralized trust network for AI models and emphasizes a concept he refers to as Payable AI. This approach is described as integrating attribution, rewarding contributors for their data, and encouraging transparent, on chain model operations. Ram positions this work as an effort to move away from centralized and opaque AI systems by supporting community involvement, verifiable data flows, and mechanisms that distribute micro payments tied to model usage.
OpenLedger’s use of OpenLedger.xyz aligns with a growing number of AI and computing projects that choose .xyz to share documentation, research, and platform updates. Many organizations in this space adopt .xyz for its short format and broad applicability across technical and nontechnical audiences. Using OpenLedger.xyz places the project within a community of developers and teams working on emerging technologies and publishing information about models, data infrastructure, and on-chain systems. You can learn more by following the platform on X/Twitter and LinkedIn, joining the Discord, and by visiting OpenLedger.xyz.
