Prepare to venture into the procedurally generated depths of the liminal levels within the backrooms, drawing inspiration from the original lore. As a regular guy, your survival rests solely on your legs and the scant items you may discover during your daring expedition, all while dangerous entities lurk ominously along your path. Every level is procedurally generated, guaranteeing a captivating and unparalleled experience with each playthrough. Each level boasts a distinct layout and different escape routes, adding to the game's allure. The game features a dynamic scenario system, where each scenario offers distinct means of accessing the backrooms, diverse levels, unique endings, and a variety of entities to encounter. Presenting an immersive and realistic visual experience, accompanied by eerie and lifelike sounds, all complemented by a full-body first-person perspective. Form a team of up to 4 friends and endeavor to escape the backrooms together. Unity is key, for the path to freedom requires collective effort and a shared pursuit of the exit, leaving no one behind. For the intrepid souls, the option to brave the backrooms in single-player mode exists, albeit without the same thrill of camaraderie. Within the depths of the backrooms, perilous entities silently prowl, so exercise utmost caution, as they possess the ability to swiftly end your journey. While communicating with your friends, exercise caution not to lose your way, as their voices may fade beyond reach. Be wary, for even entities possess keen hearing, thus maintaining silence during critical moments becomes imperative.

Adventurers, it’s time to unite! A dark force has taken over the underworld in the RPG dungeon crawler, Demeo, and it’s a world you’re not likely to survive alone. Demeo is a cross-platform cooperative adventure for up to four players that recreates all of the magic and camaraderie of gathering around a tabletop with friends to do battle against the forces of evil. Assume the role of the eagle-eyed hunter, mystical sorcerer, deadly assassin, protective guardian, melodic bard, powerful warlock or boisterous barbarian. But choose your heroes wisely in this cooperative adventure, for once players have accepted their quest, they must work together to vanquish the unholy force that corrupts everything... or die trying. Our story originated inside the Elven Necropolis — but that was just a mere overture! Following the first Demeo adventure, The Black Sarcophagus, players have already explored the Realm of the Rat King and Roots of Evil — and with our latest adventure, Reign of Madness, they’ll venture into the town of Ends for the first time and meet Demeo’s newest playable character Uhrak, the Barbarian who is never more than a grappling hook’s throw away from the action. Gathering friends for a night of casting spells, rolling dice, and moving miniatures are some of your fondest memories -- and now you can have this same experience with players from anywhere in the world! Demeo recreates all the fun of tabletop dungeon crawling in the digital space by connecting players for table talk, treasure hunts, and plenty of turn-based action with infinite replayability. It’s dangerous to go alone! Grab your friends and assemble a party, because exploring the depths of Demeo requires strategy, cunning, and teamwork. Every character has their own unique approach to managing magic and monsters — and they’ll need to work together if they want to survive! Take the mantle of the hunter, sorcerer, assassin, guardian, bard, warlock or barbarian, all with their own unique abilities and skills, and use them wisely if you are ever to vanquish the darkness that is Rackarn and Alfaragh. Take your battle against the forces of evil with you wherever you go! Demeo: PC Edition has been optimized for Steam Deck, bringing the game’s native controller support to Valve’s popular handheld device. It’s never been easier to jump into a game of Demeo with friends right in the very same room. Go on an adventure with friends on PC and other VR devices! Cross-play multiplayer lets you play Demeo with players wherever they are, including Oculus and consoles — and with Demeo: PC Edition now available, you can even play with friends who still need to equip a VR headset of their own!

Don't fight, robots! Destroy our city! And pay off the debt...<h2 class="bb_tag"><h2 class="bb_tag">about Demolition Robots K.k.</h2></h2>This game is a 4-player non-fighting robot game, kind of a speedy party-couch action with the deception essence of a werewolf game. You are the pilot of a giant robot and destroy many buildings on the level faster as possible. You earn wages (points) for each destroyed building, and the player who reaches the target number of points the fastest wins. However, the normal incomes aren't enough to win. In order to get many the points at once, you must achieve the hidden goals prepared for each player without being revealed to the other players.<h2 class="bb_tag"><h2 class="bb_tag">world Of Demolition Robots K.k.</h2></h2>You live in a peaceful world that has triumphed over a giant alien invasion. To pay off your debts, you take a job at Demolition Robots K.K., a revolutionary urban demolition company that utilizes battle robots paid off by the private sector. However, your debts will not disappear immediately after hard work. There must be a more efficient way... Players must not fight each other directly! Robots are company equipment. You may not hit another player because you do not want him to take your wages. You will be considered to have intentionally damaged company equipment and your wages (points) will be deducted from your wages. However, this does not apply if you &quot;accidentally&quot; hit a steel ball or crane that was on site. Now you know what to do... Earn money through &quot;illegal side job&quot;, and whistle-blowing other players! You have debts that cannot be repaid with the wages you earn in your regular job. If a shady character offers you a &quot;illegal side job&quot; at the start of the game, you might want to jump on it. Has the company told you not to tear down a particular building? No, it is possible to make more money by tearing them down. Do you want a certain package delivered while you work? If you do it secretly, your co-workers won't even know you're there! However, be lenient with yourself and strict with others. If you think another player is doing &quot;underhanded work,&quot; turn him in to the company after the round is over. Hopefully, that player will be fined and you will get your reward. Remember, that the situation can be reversed in either case...
