Portal done Half-Life Source is a mod in which you are required to play through Portal 1's maps with the weaponry, movement and glitches featured in Half-Life Source. There are no portals featured anywhere throughout the game (at least, not as Aperture Science would define them), and you also can't pick up physics props, requiring you to solve puzzles differently and exploit many of the glitches featured in Half-Life Source's game mechanics in order to progress through test chambers. The game is designed to be playable from start to finish without any use of console commands, cheats, or save-load abuse tricks (with otherwise impossible obstacles instead resolved with breakable glass and the teleporters featured throughout Lambda Core), although it's highly recommended that you make a variety of quick saves throughout the game in case you get stuck.
