CrossOver Game Engine
CrossOver is a free online video game utility software that enables you to use a crosshair over any first person shooter game playing on Windows. Developed by Lacy Morrow this simple, lightweight tool provides highly customizable crosshair overlays which can be used directly on your computer screen. You may also use CrossOver with the popular Counter Strike or Team Fortress 2 game engines. CrossOver allows you to change the crosshair at any time and change its resolution, allowing it to be perfectly in sync with your game playing experience.
CrossOver was created for those who were not satisfied with the default game view provided by the mainframe computers of the era. With the advent of the X Window operating system, many games developed for PCs were rendered useless because they didn't have graphical support built into them. CrossOver is different; it has full cross-platform support. It can use the game's engines, as well as its own graphics rendering code. Therefore, even if you have an old PC or a gaming console, you can play any type of PC or game using CrossOver.
CrossOver allows you to save and load various game configurations, allowing you to swap between game types whenever you like. CrossOver also comes with a number of cheats and codes for you to use, as well as tools to analyze and test your game play. This is one of the few utilities that can help you test out what you have got when you are not actually playing the game, which is a nice feature for those of us who love to test out our skills online. The best part is that you can use all these features for free!
