Hotel Romanstein 2: Xmas Party is a mod for shareware Wolfenstein, made by Mr. Choi. It was released on December 21, 2005.
Initially only available in 4GL, Chris Chokan released a DOS port three days later.
Though still carrying a slightly burlesque feel, the mod is essentially Christmas-themed with the female antagonists now wearing Santa hats, and graphics edited to fit a jolly mood.
The mod features 10 new levels, some of which have wide open spaces. Coding changes include the static object limit has been raised.
