AWP was developed and released by Resurrection Studios under the anger of Apocalypse Weekend, the official Postal 2 expansion. While it was called an expansion, many fans of the series and the AWP developers themselves stated that it was not, as it did not add anything to the original game and was rather a "sub-sequel" in the series. The new weapons and extra gore featured in the expansion were not available to use and implement in Postal 2 without extensive modding and fileswapping. Originally under the name AW7 (Apocalypse Weekend 7), it imported the Apocalypse Weekend features such as the extra gore and weapons over to the original, as well as the two extra days; making the two games a seamless, single experience. As many more features were introduced, AW7 was renamed and finalised to AWP (A Week In Paradise).
AWP combines both Postal 2 and its expansion Apocalypse Weekend together, thus giving the player access to the Apocalypse Weekend weapons, days and extreme gore whilst playing the original Postal 2. On top of this, more weapons from other mods such as Eternal Damnation and M@DJ@cK@L's mods are ported in. Civilians now have more models, as well as accessories such as handbags and hats. Police are much tougher and sport deadlier weapons. Extra gore on top of Apocalypse Weekends' has also been implemented, with the ability to expose internal organs and hack off more body parts.
- Dogs can no longer fetch weapons or human heads in this mod, altough they can still be fed and befriended.
- The mod is very buggy, even the latest available version. Due to this, the game may frequently crash when too many events happen that chew up the game's memory, such as many bomb explosions going off at once, or too many toxic clouds from weapons are active. Even too many weapons or dead people can crash the game sometimes.
- This mod is the only one to include playable arcade games, as the "Zombies ate my neighbors" arcade game in Eternal Damnation does not load properly.
