Portal 1 Multiplayer In Portal 2 Co-op
PuzzlePlay the entire portal 1 campaign in portal 2 multiplayer.
This is a free Portal 2 Community-Made Mod, it is Portal 3, which also includes the "Perpetual Testing Initiative", which is also expanded. The items are the high energy pellets, they now replaced the deadly lasers with high energy pellets. NOTE: The deadly lasers are the disabled devices. This mod is developed by Valve, but created by Portal2Player1. Valve needs to make the same puzzles from Portal 1 and 2 in Portal 3, but Portal 1 Levels in Portal 3 will have portal 2 lasers, and Portal 2 levels in Portal 3 will have High Energy Pellets. Again, the lasers are also in Portal 2. but are broken and disabled devices. Portal 3 Levels will have different test chambers than Portal 1 and 2, which starts back in the deystroyed test chamber 00/19 from Portal 2
