    Impostor

    Impostor

    An open source reimplementation of the Among Us Server

    Impostor is an open source reimplementation of the Among Us Server, written in C#. It is among the first Among Us private servers with support for Steam, Itch, Android and iOS. It is a full replacement of the game's official server, so you can expect all of the game's features to be included, and the same fun playing experience. The difference of course is that you get to play on a private and secure server. Impostor has plugin support as well as a server-sided anticheat feature. You also have the option of playing on a server hosted by someone else.

    Advanced Traffic Simulation

    A mixture of game and simulation for public transport.

    This project is about a game and a simulation to work together. The focus lies on public transport. Manage your line network in your home area. Upgrade your vehicles, build new roads, deal with accidents or plan replacement busses for railroad construction works. But it's also possible to drive the vehicle yourself or just walk around the world and enjoy your line network. By vehicle we mean: train, tram, subway, bus and monorail. By using an addon structure it is possible to customize the whole world or even include non-existing means of transport like the hyperloop. Plan, manage and drive all together in multiplayer. Either competing or cooperative. Discord: https://discord.gg/P3SbVuD VSTS: https://advtrafficsim.visualstudio.com/
