Railgun

It is a free Roblox physics sandbox by Ragdoll Shenanigans. Ragdolls react to players and to each other, can fight, and can be squished, thrown, crashed, and injected with mutations that unlock journal entries. Weapon variants unlock by playing. The root place is 135264274035761.

No developer-published code string was found in the game description, the Ragdoll Shenanigans events, or the pass listing checked on 11 November 2026. A code button was also not confirmed in recorded gameplay. That is not proof a code can never exist. Do not treat Daily Rewards, group rewards, journal pages, or weapon unlocks as codes, and do not use codes from a different ragdoll game.

On the recorded PC layout, open Test Chamber 01 and press one labeled mutation button. Watch the body change, then look for a green NEW JOURNAL PAGE message and open Journal on the left. The readable panel labels are Wings, Long Arms, Big Head, Tentacles, Diamond, Long Legs, Bug, and Plant. A walkthrough describes unlocking a matching syringe after a discovery.

The developer event City and Elementals is scheduled for 14 November 2026 at 18:00 UTC through 16 November 2026 at 18:00 UTC. The listing includes new guns and melees, elemental abilities, a weapon-progression rework, a City map, more vehicles, secret quests, avatar clothing and props, a lollipop melee and silly accessory bundle, multiplayer improvements, and bug fixes. The start time is still in the future as of 11 November 2026, so those lines are not live instructions yet.

The Roblox experience record checked on 11 November 2026 has VIP server creation turned off. The root place metadata also lists a one-player cap, while a second place is named {Multiplayer Server} Ragdoll Research and the developer description says full multiplayer. Use the in-game Servers menu rather than a private-server purchase.
