Missing Information aims to recreate Valve's original Half-Life 2 storyline found in Raising the Bar.
This game was extremely good, it has most of the content cut from half-life 2 and has its own map (MI_BUILDINGBLOCKS) were you can test the spawnable entities.I would give it a ten but it lacks some content such as the Combine Guard and Cremator it also lacks the manhack arcade. I recommend this mod for anyone who wants to legally play a beta version of half-life.
I think that's pretty cool how these people went out to re- create the Hl2 beta and E3 maps, along with the other things such as working beta npc's. My only problem with it is that there are a few bugs, but that isn't much of a problem with me.
