Operation Flashpoint: Dragon Rising is a direct sequel to 2001's hit combat simulation game Operation Flashpoint: Cold War Crisis and the expansion pack Operation Flashpoint: Resistance.
Custom EntityDatabase adds new variants of vehicles, weapons, statics, crates, ammo, units, echelons and fireteams. It will change parameters of existing vehicles and weapons to make them use realistic values for ballistic and engine parameters. Improved EntityDatabase is making weapons more deadly, it is also doubling the bleed out time.
Copy downloaded EntityDatabase.xml into your Mission Editor/Database folder from your game directory and replace old file. You may want to save default EntityDatabase.xml. From now on every your exported mission will use new database, this means you don't need to add anything more to mission if you want to share it with new content. Improved EntityDatabase is needed only for mission makers. It will work with every version of the game.
