Warhawk Unlockables and Glitches (PS3)

Warhawk is a futuristic arcade-style flight-combat game for the Sony PlayStation console, developed by SingleTrac and released by Sony. It was originally released on November 10, 1995, and later re-released as part of Sony's Greatest Hits lineup. A multiplayer-only remake of the same name has been developed by Incognito Entertainment; it was released on Blu-ray disc and as a digital download for the PlayStation 3 on August 28, 2007. Warhawk is an action/simulation game built around a futuristic VTOL craft.

The player maneuvers with 360 degrees of flight control through 6 unique levels. Weapons include fire off lock-ons, rockets, multi-fire swarmers, and plasma cannons. Enemies in the game vary from being tanks and aircraft to massive fixed gun emplacements and futuristic robots, to name a few. In certain areas of the game, enemies continuously respawn to challenge the player until they swiftly complete the mission objective. There are no saving or loading features. Instead, a password is presented each time a level is completed.

UNLOCKABLES

GLITCHES

Extra missiles

When you get the single shot homing missiles in an airplane, you should only be able to get a total of three. However if you pause game play, wait about fifteen seconds, then resume the game, you should be able to pick up three more. This will only work up to nine missiles.

Updating stats

Due to a server error (partly because of global servers), your stats usually will not update immediately. To see your stats, log off for four or five hours, then log back on. Your stats should be updated.
