An adventuring guild hall was built in the country side, atop the mouth of an ancient portcullis. Beyond the steel and stone gate lies the twisting expanse of the DUNJUN, filled with vile monsters and deadly traps. Aspirants travel from lands near and far to delve into the DUNJUN’s timeless depths, seeking treasure, knowledge, and fame alike. Time has forgotten the DUNJUN’s origins, but many a rumor escapes the lips of bards, scholars, and soldiers. In DUNJUNGUY, a party of up to four friends can test their might against the hordes of creatures in the DUNJUN. Combining Action RPG mainstays with mechanics familiar to Roguelike fans, players can choose abilities, find powerful gear, and navigate procedurally generated environments while staving off impending doom. DUNJUNGUY delivers a cartoony visual style, contrasted by its exploration of macabre and moody touchstones. In this couch co-op dungeon-crawler you and four friends venture into the depths of a dark dungeon where enemies, traps, and loot await! Play up to 4 different classes, level up your abilities, and explore a variety of unique and handcrafted dungeons where peril awaits around every turn. After surviving each round of the DUNJUN your party may find respite in the Tavern, a place to sell loot, upgrade your player, and chat with the locals. Once you have proved your mettle as a brave adventurer DUNJUNGUY himself may permit you to enter the deepest depths of the DUNJUN where fame, glory, knowledge, and riches beyond your wildest imagination await.

Journey with your friends in the world of Ferromon Together and take on the 10 towers with over 140 Ferromon to save the world's inhabitants from the Tainted. The entire game is free to play, with a cosmetic pass DLC available to those who want to support development. Work together with your friends to build, craft, and train to progress in this fun to play RPG. First of all of course is the combat. You will be exploring with your friends and catching many monsters. each monster has certain unique stats to help it in battle As you can see in the FerroBook, each Ferromon has 5 stats: Health, Attack, Speed, Healing, and Jamming. Health, attack, and speed work how you would imagine them to, while healing determines how much extra healing is applied to you, and how much overflow healing goes to your injured party members. In order to counteract healing specialized monsters, Jamming lowers the enemy Ferromon's ability to heal. There are 10 types in Ferromon, each with their own strengths and weaknesses. Having a balanced team of Ferromon allows you to stand up to any challenge. Each Ferromon has a primary typing, although some have an attack typing. This attack typing doesn't contribute to weakness; however, it adds 80% damage to moves used of that type. All Ferromon have a set species skills. They don't learn new skills as they grow stronger. In order to learn new skills, Ferromon undergo absorption by using the absorption stone. This stone allows Ferromon to absorb other Ferromon to gain one of their skills. Ferromon with lower stats tend to have better skills, so absorbing a good move from a low stat monster into a high stat monster is favorable. Once some Ferromon reach a certain level, if you have an emergence stone in your world, they can emerge into a stronger form. There are two tiers of emergence stones. For stronger Ferromon, you will need the second-tier stone. In order to get useful world utilities, you craft them using drops obtained by defeating wild Ferromon of a certain type and emergence tier. That leads me to the building system! Take control of the backpack drone to place and destroy any placeable items you have crafted. In addition to utilities to help you get stronger, there are walls, doors, floors, fences and more. Build an awesome base with your friends. It's also advisable to build around your utilities, as nefarious things can happen at the end of the world's cycle. Now arguably most importantly, what exactly can you do with your friends? The answer is everything! Every non pvp battle that occurs in the world can be joined by 9 players! This is done through the Link System. When you are linked in a battle, all damage, jamming, and healing to the enemy is replicated, as well as half the damage to your monsters and half of friendly healing. This allows you to strategically work with your friends to take down strong enemies. Work together to clear the 10 Towers that are spread out across the map, and the final boss that comes after that!
