According to the press release: Answer the call of duty to take up arms against the Goblin-Cong, trudging through a napalm-scorched battlefield with a bad company of up to four wizard GIs, and earn new medals of honor and achievements as you eliminate scores of enemies with not-so-wizardly machine guns and a new napalm Magick, liberate prisoners from POW camps, and escape to a Huey before it gets shot down by a pistol—all of this, of course, in your stylish robe fatigues and hood-friendly helmet.
The DLC also includes:
• Vietnam themed game world with a twist
• 2 Challenge maps (1 scenario challenge & 1 survival challenge)
• New Vietnam themed enemies
• Many new Vietnam era weapons
• Stylish GI Wizard robe
• New Magick – Napalm strike
• Innovative and dynamic spell casting system with thousands of possible
combinations
• Up to four player co-op in all game modes as well as single player option
• Experience the parody and satire of a cliché fantasy world/jungle war
The best part is that only one buddy needs to have the DLC for his friends to enjoy the DLC in multiplayer.
