Critical Mass is a single player Source mod. A four-player coop mode may be implemented depending on the modability of Left4Dead. This mod has no storyline connection to that of the Half-Life franchise, or any Valve product. The story is rich and polished, see the official website for more elaboration. In short, you play the role of Logan Bowes, a captain and squad leader in a future military. The squad consists of four characters, so if the coop mode does get made, each player will fill the roles of one of the four squad members.

"Son, you’ve got to fight for your country."

Logan Bowes hears the words echo through time’s ear. These were the words that haunted him, the only memory he had left of the man who was his father. He'd spent the last dozen years unable to recall any memory of Stephen other than this tense moment.

"Yes sir" young Logan replied, terrified by his surroundings. A gust of wind rose up and partially obscured the sights and sounds of screaming and crashing all around them. His father’s arms were outstretched, grasping onto Logan’s shoulders. His eyes pierced his son, scanning for the level of bravery his son was exuding. 17 year old Logan met his father’s stern gaze.

"I won’t let you down, SIR!" The boy was trembling. He wanted to tell the truth, but fear of repose occluded such a response. Logan's mind wandered momentarily to the cliches of duty that had been pounded into his head for an untold number of years. "Stay on point, do with honor", what a bunch of ... wait!, why did dad just say-

A searing flash of light arose and blanketed the city in white. The screaming and crashing got louder and more urgent. When Logan was able, he peeked up and saw the sun - rising up from the city. Logan's attention returned to his father who, fishing in his pockets, pulled out a small box-shaped device that Logan recognized. He began a protest, was cut short by a firm jerk on the arm. His father forced the object into his trembling hand "You know how to use this". Logan, sobbing, glared into his father’s eyes, and knew his dad was about to say ‘Goodbye’. He pushed a button on the device. His father’s mouth opened.

"Yo Bowes, what up dog?"

Captain Logan Stephen Bowes, age 29, sits upright with a jerk. Recognizing the voice of his second in command, he stretches his eyes by closing them tight and quietly thanks Marcus for saving him from the inevitable ending to his only dream.

"Yeah – What do we got, bud?"

"Oh we almost there."

Most likely not dead, but BoX was the ONLY one working on it thus it has been put on HOLD.

brian4, you're absolutely right, it can be done by any decent coder. I suppose I was thinking in terms of not having a coder when I posted that. If you're serious about helping out, that would be great. Currently, the four player models don't exist, but I look forward to tackling that little problem soon. Message or E-mail me if you decide how involved you'd like to be in the development. Thanks! -BoX

Actually, I was just willing to make a patch that enables AI for the newest SDK, when it comes out. Too busy with my own mod to take on a second one.

Why would coop depend on the modability of left 4 dead? It's very possible to enable AI in the multiplayer SDK. There's even a patch on to help you do it. (Although it may not work on the new sdk update that is supposed to come out soon.) If not,I'd be willing to help with that. It'd be a shame for a mod as promising as this not to have coop.
