2023 has landed and we’re kicking things off with a chilling new entry in the LambdaBuilds line-up - Tundra, in which it’s your job to make us shiver with wintery environments, guest judged by the mastermind behind one of the coldest mods of all, Breadman from Entropy : Zero 2!

Arctic environments are some of the rarest seen in Half-Life and it’s mods. Whether it’s because of a real lack of examples provided by Valve themselves or the lack of materials to be found in any one Valve title, this kind of scenery is rare despite its presence in Half-Life 2 pre-release material and what could have been the fabled Episode 3.

So, for our fourth theme, let’s fill in the gaps and bring the cold with a competition focused on producing this exact kind of environment! Using the snowy assets we’ve collated from across all Valve’s titles as a basis, what comes with the good ol’ Source SDK, and anything else you can rustle up yourself, it’s your job to turn down the heat and bring in the cold. Puzzle, horror, action, the specifics are up to you - but make your players appropriately cold for the time of year.

A special thanks to Dustfade, the developers of the recently released Source powered multiplayer game Military Conflict: Vietnam for sponsoring this competition!
