Crasher Dupe | Gmod Server

1. What It Is The “server‑crasher dupe” is a user‑crafted contraption (usually built from props, constraints, and a few scripted entities) that, when spawned on a Garry’s Mod server, can cause the host to freeze, lag dramatically, or even shut down. It exploits the way the Source engine handles certain physics and networking calculations, forcing the server to process an overwhelming amount of data in a very short time. Bottom line: It’s a deliberate denial‑of‑service (DoS) tool for a specific game environment, not a gameplay feature. 2. How It Works (High‑Level Overview) | Component | Typical Role | |-----------|--------------| | Massive Constraint Chains | Creates an exponential number of physics updates. | | Duplicated Scripted Entities (e.g., prop_physics , gmod_wire_* ) | Forces the server to run many script hooks per tick. | | Recursive Duplication | A dupe that contains copies of itself (or of other heavy dupes) can quickly balloon the entity count. | | Network Flood | Each physics update is broadcast to all clients, saturating bandwidth. |
