War Rock is a free massively multiplayer online, modern tactical first person shooter (FPS) where players have the option to purchase a wide variety of gameplay enhancing items, services, and products.

Warrock features several maps, several vehicles and aircrafts, and over 25 different weapons. The player has the choice of playing on the NIU team or the Derbaran team. The player has the choice of a number of classes, with each class having a different weapon set, and ostensibly different role and tactics. The game also features a ranking system. They also have an in-game Item Shop where the player can 'purchase' more powerful weapons using e-dinar you earn by playing the game. Some weapons can only be bought if the player uses real money to pay for a 5th weapons slot. The player can also use real money to pay for other benefits in the game in the future as well.

In order to combat growing levels of cheating in the international version, the game now uses the PunkBuster. The Korean version uses GuardCAT. So far people have been able to make bypasses for GuardCAT effortlessly, yet there has been no proof of a hacker in the International version since the release of PunkBuster in the game. However, it can be difficult to tell a hacker from a legitimate player. Developers and players with special accounts have access to extra weapons and items. Also, WarRock contains many bugs, glitches, and exploits, the abuse of which is definitely cheating, but not necessarily hacking. A check of the official forums at any time reveals dozens and dozens of reported hackers, but it is unknown how many of these are actually valid.

Previous versions of WarRock had rather severe security issues. They were extremely vulnerable to hacking through the simple use of a packet editor, not to mention the 2-3 availible "trainers.

WarRock players can pick from five basic classes:

• Military Engineers: Millitary Engineers's standard equipment is a Colt 45, MP5 and Spanner. Upgraded primary weapons include a P90 Customizzato, Uzi, and a G36C. Their primary function is to repair and maintain vehicles. They are of no use in Mission Mode because they carry the same weapons as a medic but medics have the ability to heal other players and themselves.
• Medics: Medics' standard equipment is with a Colt 45, MP5 and Medic Kit. Upgraded primary weapons include a P90, Uzi, and a G36C. Their primary function is to provide medical aid as needed. The Medic's ability to heal is somewhat limited in that the damage is repaired incrementally. and severe damage requires multiple treatments. Furthermore, the MediKit must recharge between healings. They have, however, advantages over the Combatant due to their ability to heal themselves. A medic can heal herself after each encounter with the enemy(and sometimes during combat) to outlast other character classes.
• Scouts: Scouts are standard equipment with a Colt 45, M24 and K400 Grenades. Upgraded primary weapons include a PSG1, Steyr AUG, and a Steyr SSG. Their primary function is to provide information on enemy units and long distance cover fire.
• Combatants: Combatants' standard equipment is a Colt 45, K2 and K400 Grenade. Upgraded primary weapons include an M4A1, G36, and an AK-47. Their primary function is to provide close range combat and support for other branches. Combatants are the main ground force and are usually followed by medics.
• Heavy Weapons Units: Heavy Weapons Units' or (HWU) standard equipment is a Colt 45, Panzerfaust 3 and TMA-1A Landmine. Upgraded primary weapons include a RPG-7 and a FIM-92. Their primary function is to immobilize enemy vehicles and armor. They are useless in Mission Mode unless they are equipped with the RPG-7. If shot correctly this weapon can do one-hit kills.
