I would like to announce a new building blocks-themed mod for Half-Life 2, Mini Wars. Everything in the mod will center on the mini theme from maps and character models to weapons. Maps will all appear to be made out of Legos and the character models will be based on the Lego guys (they won't match the Lego guys exactly for copyright reasons). There will be many unique weapons, such as a flame thrower that operates on matches and lighter fluid, Snap 'n' Pop grenades that explode on contact, and a sniper rifle made out of a mechanical pencil.
