Global interactive entertainment company Codemasters announced today new details for the co-op multiplayer mode of Soldiers: Heroes of World War II, the company's much anticipated real time strategy game. Developed exclusively for PC/CD-ROM by Ukrainian company Best Way, Soldiers will be released in the U.S. on June 29.

Set to go beyond the call of duty and provide players with an intense online experience, Soldiers offers an innovative co-op multiplayer mode enabling up to four players to work through any of the campaigns together. The game allows players to handpick their troops and take on any of the tactical action missions in the campaign.

Complementing its single player offerings, co-op multiplayer functionality in Soldiers offers its own game play outcomes and greatly increases the tactical options available to players.

Following the game's release, Codemasters will continue supporting the Soldiers community with additional content in the form of free downloadable upgrades. The first upgrade will incorporate a new multiplayer mode, Versus, and offer third party online matching software from GameSpy Arcade. The free, fully functioning service will make it easier than ever for Soldiers fans to find opponents and compete head to head in any of the game's innovative multiplayer campaigns.

The inaugural upgrade release will also form part of Codemasters' ongoing anti-piracy and gaming security program. The upgrade will only function with an original copy of Soldiers and aims to safeguard the game play environment against others using cheats or those who unfairly hack into the Versus multiplayer game.
