The Last Resort mod for Swat 3 helps improve the look of the game on modern computers. This is accomplished by a combination of custom game launcher, modified game files, and replacement high resolution textures. You only need to re-download Version 0.7.4 if previous versions didn't work for you since the v0.7.0 update was released. Works on all versions of the game (retail CD, GOG.com, and Steam version).
The main goal of the "Swat 3 Last Resort" mod is to upgrade Swat 3 to take advantage of modern video cards and monitor sizes. When the game was first released 800x600 was the standard resolution and most video cards only had 16mb or 32mb of video memory.
The Last Resort mod is completely transparent and won't damage your Swat 3 install. All of the files are additive - nothing gets replaced or written over. You can easily restore your game back to default Swat 3 by clicking the on/off button on the Last Resort Launcher. The installer will also automatically make backups of all your main Swat 3 files for safety.
Version 0.7.4 contains a fix for a bug with the installer that prevented the mod from installing properly on systems that already had Swat 3 installed.
