About Mission To Fission

Nuclear fission simulator. Control A nuclear reactor, balancing Uranium fissile material. The game features a oversimplified reactor and the R.B.M.K Reactor in Chernobyl. But more reactor types are on the way. This game is in early alpha, so try it out and suggest the direction for the final game. Thank you!This game is from the YouTube series "Vision of Fission" from Higgsino.

Didn't think I could be disappointed at this price, however........ Very poor. UI is janky, gameplay is limited (and glitchy) beyond reason. Devs do not care (I have reached out to them). I very much doubt this game is going to improve. I rarely give a game a bad review (check out my past reviews), but if one is deserving of it, it would be Mission To Fission. Terrible. Please disregard the positive ratings. Based on my research, these all come from friends of the "devs" ("devs" being a word I use reluctantly in this case). I cannot get over how much of a piece of sh!t this game is. I have played many, many games in my time, but this takes the cake for the most poorly thought out and designed. As soon as you load into the game, you know something isn't quite right. I cannot disapprove enough - buy at your own risk, you will be disappointed! Edit: There is more! I uninstalled this junk from my library two days ago, and it always launches in the background when starting my PC. Additionally, it interferes with my other processes. Likely to contain viruses; will be checking my PC after posting this. Requesting a refund - first time I have done that in six years. AVOID!

Game is cool, inspired me to try making a fission sim of my own. Only real problem is that the developer/creator hasn't updated it in about 8 months. I think the Light Water Reactor is pretty neat.

Games like Undertale that remember what you did

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
