Halten Sie! is a mod for registered Wolfenstein, made by Laz Rojas. It was released on December 24, 2002.
Based on an earlier Mac scenario, the mod features 10 levels, played on Episode 1, and a number of changed graphics and sounds.
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.
No source code changes are featured, and it is thus playable in SDL.
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.
