Game is fun, works great in coop, has a lot of potential. I hope that the continue development. Since it is early access here are some requests from my group: - Workshop support + map editor - More variety of maps, guns, enemies (workshop will help) - Classes skill trees instead of random (workshop will help) - Late game usage for scraps and such. - Endless mode (more perks?)
Been loving this game since its released; I don't know how they do it, but selling a game at this price while adding free friend passes, minimal latency and coop mechanics really tells you how invested these devs are. I also don't mind the roguelite idea in the endless mode. It keeps the replay value of the game. My only suggestion I have is to add a trigger on/off Roguelite vs progression system to fill in all players' preference. Otherwise, an easy 9/10 game for me.
Solo Experience – HUNK Simulator Co-op Experience – Resident Evil 1, but the gang actually sticks together. Whisper Mountain Outbreak is very clearly inspired by classic Resident Evil, and honestly that’s a big reason why I enjoyed it. The atmosphere, exploration, and survival gameplay feel like a love letter to that era of survival horror. I played through the full game and made it to the endgame where the endless horde mode unlocks. The core gameplay is solid, and the co-op experience is where the game really shines. Running through the map with friends, managing resources, and trying to survive the chaos captures that tense survival horror feeling really well. And from the name alone — “Outbreak” — it's clear the game is also drawing inspiration from Resident Evil Outbreak. You can definitely feel some of that DNA here. Right now the experience is more of a contained roguelike adventure, and for that scope it honestly nails it. But it also feels like the foundation of something that could grow into much more. Something like a non-roguelike mode similar to Resident Evil Revelations' Raid Mode would add a lot of longevity — structured missions, progression, and replayable objectives. If the developers ever wanted to go bigger, I could even see this concept evolving into something closer to what Outbreak originally hinted at — maybe a small open town or city where players survive together, gather supplies, craft items, and complete dynamic missions. Think something like No More Room in Hell 2, but instead of a single mission that funnels players toward a central objective over time, the CRC could explore a dynamic world. Imagine a small town or open environment filled with characters, exploration, events, and lore. Players could scavenge, survive, craft items, and encounter dynamic missions while learning more about the outbreak. A world like that could go in many directions, paying homage to classic survival horror while also building its own identity and story. It could even allow multiple interpretations of how the outbreak actually started, adding mystery and replayability. Even if something like this existed as a separate or optional mode, it would give players a reason to stay long after completing the main experience. Because the bones of this game are already great, it just needs that extra push to turn it into something a lot more people will want to jump into. One thing I’ve noticed from reading feedback online is that a lot of players aren’t fans of the permadeath system, and I can understand why. It’s especially rough after finishing a great run with friends. For example, we pushed a full run all the way past Wave 69 in Horde Mode, and while that was fun, losing everything afterward can feel discouraging. Enemy encounters can also start to feel repetitive over time, and the environments could benefit from more diversity and tactical options. Otherwise the gameplay loop starts to feel like that same HUNK Simulator — moving from point A to point B while resources and luck decide whether your run survives. That said, the game is still in Early Access, and the foundation here is strong. The survival horror DNA is already in place, and if the developers continue expanding modes, environments, and systems, the sky really is the limit for where this game could go. Whisper Mountain Outbreak has the survival horror DNA nailed down. It just needs more content and breathing room to let that outbreak truly spread.
The game feels very solid overall; however, co-op players who aren’t the host lose their progress when the game is reloaded, even if they survived the run. This is disappointing, especially after a strong session you’d want to continue, would love that to be fixed before we continue playing it again.
