Dissolution is a science fiction, single-player mod for Half-Life 2 that mixes adventure and action game-play. Set in the year 2089, in a universe dominated by a mega corporate entity, Xterrier, the player awakes in a hidden lab to the voice of the mysterious Wilson. Guided by Wilson, the player must make their way through the ravaged Xterrier 581c colony, making use of any and all resources they can get their hands on in order to survive, all the while attempting to piece together the events leading to the colony's collapse and their own identity.
Although fights are boring and often unfair, and the map design is somewhat lacking, this mod shines through its atmosphere and story. While the story itself could easily be the plot of a B-Movie it is how this story is told and how much background info can be found throughout the mod that creates a densley packed atmosphere.
