A LoRA that imitates the style of the first Half-Life game. It currently is somewhat bad with people and aliens due to the dataset being used, but it works pretty well with environments. At lower strengths, it becomes more of a generic early 2000s video game style LoRA.
It's recommended to use phrases like "A video game screenshot from Half-Life featuring ..." or "Half-Life screenshot of ..." for best results. If the results look too smooth, try adding "low-poly". At full strength, it may mess up textures and produce artifacts, so stay at around 0.8-0.9.
To control the HUD, try putting "The HUD is visible." to the positive or negative prompt. To show the first-person weapon, try "The player is holding a crowbar/shotgun/revolver/gluon-gun/etc." to the prompt. It may mix with other characters in the scene, though.
