Halten Sie! is a scenario for the Mac version of Wolfenstein 3D made by Laz Rojas. It features 11 new levels and various new wall textures. It later inspired a WolfenDOOM scenario by the same name, as well as a PC and ECWolf port.
Once again, you must escape from a dark and evil Nazi prison -- only this time, the fate of the free world depends on it. The Nazis are planning a secret attack that might decimate the Allies, and only you know about it. Can you warn them in time?
Halten Sie! was ported to the PC version of Wolfenstein 3D by Laz Rojas on December 24, 2002. The port features 10 levels, played on Episode 1, and a number of changed graphics and sounds. Level 2 was dropped so that the level set could be contained within Episode 1.
As with Rojas' only other Windows/PC mod, Escape from Totenhaus, the VGA is not functional on all computers, and using the original Wolfenstein files is recommended.
This mod was ported to ECWolf by AstroCreep in 2015. It features updated features such as DECORATE copies of the SOD bosses and a remake of the missing 2nd level from the original Mac scenario. Available in original style or in an upgraded HD version with 128x textures and global light levels/flats.
