“Game is yet another tech demo and story isn't concrete. Again, mods is where its at and if you're not playing with friends with the multiplayer mod, the game gets very old and stale fast. Again, they love climbing as…”
“Really loved bonelab, found it an enjoyable game but i feel it felt disapointing, its a 40 euro game with a campaign i found really boring and underwhelming, just tons of filler levels and had to restart multiple times…”

“old and no update, but still ♥♥♥♥♥♥♥ awesome. campaign isnt that bad, lowk its good why hate the game with the mention of boneworks, just go play that, dont give this game bad reviews for no reason”
“Wow. Just wow. I could genuinely talk about how good this game is for ages. So lets get started. First of all, the bonelab storyline is perfect. There are 15 levels of the story and all of them have puzzles, combat,…”
“Avatars can be a little gooner but overall is a good game minus the fact that one of the gamemodes is broken. Shipping yard is broken but a mod can be installed to fix this. Overall once again great gameplay/story…”

“I miss playing this game but I feel Ive done everything I can. Peak multiplayer mod in 2023 but a worse campaign than Boneworks”
“This game is ♥♥♥♥♥♥♥ awesome the best part is when you get in ur griefer stage wich only happens if u get bonelab fusion (free online mod). In singleplayer the game is also VERY FUN. You can do things like sticking an…”
“Pretty good game, id highly recomend mods after you finish the game, and if you download a multiplayer mod be ready for some interesting interactions.”

“I don’t get the hype around this game. The physics are janky, the parkour is horrid, and the only good thing about it is the modding community. It ran fine—I can’t say there are any technical problems—but there’s a lack…”
“i can run 190 fps ultra settings great physics great avatars enjoyed the campaign not as much as a upgrade to boneworks because boneworks was WAY better anyways great game”
“A small peek towards the future of sandbox creative community driven VR games. The most fun I've had on VR in a long time. For a 5 year old game it is worth it in my opinion. Runs well, pretty much no lag or major…”

“bought it expecting a simple sandbox vr game its like a whole masterpiece especially with fusion it is a little laggy though”
“|| Review || Great game, campaign is kinda ass though, but that's not the point of this game, the point of this game is mess around in a sandbox area with mods. If you cant handle the low dopamine levels of the…”

“bonelab is cool but the story is really confusing and still dont know the story, driving cars is really wonky and the gokart level was torture for me, but other then that the game as a sandbox game is dry unless you add…”
“Gotta be honest, I prefer Boneworks, I think the original is phenomenal, you can feel Bonelab is done a certain way to be able to run on standalone as well. This said I totally recommend this game as well, It's very…”
“Bad hand tracking. Your wrists are permanently stuck in a broken position so everything you pick up will be hard to handle. Thought this would be one of the sharper controlled games but it works like ass.”

“Beyond Sandbox burned me so badly that i appriciate this game now. used to be really bad with its sdk, but now id say its worth your time with fusion + the extended sdk that the community made, can def lose alot of time making stuff for this game.”
