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.
The architecture hearkens back to the days of the original Quake. However, this is offset by including a great deal of dynamic lighting, awesome sound and music, and some tough action sequences. The whole thing feels inspired by Bioshock or (to a lesser degree) Dead Space. I truly enjoyed the horror elements and the unique new enemy to fight (not spoiled here). I think the horror elements could have been greatly expanded upon; if only the mapping had been more unique and expansive, the mod team could have built some breathtaking horror-inducing set pieces.
The mod is very difficult because citizens are naturally more aggressive than Combine soldiers, so play this one on Easy mode, even if you are used to playing on Hard mode. I was very thankful that the shotgun is fully automatic.
