According to a recent press release from Deep Silver, the upcoming Homefront: The Revolution will have a 30+ hour campaign. Not much else was said specifically about single player, but it's good to see the developers righting the wrongs of the previous Homefront game, which had a woefully short single player experience.
More was revealed about the cooperative mode, Resistance. Here's what they had to say:
Form a Resistance Cell with your friends online and wage guerrilla warfare against the KPA military in thrilling narrative-driven missions across occupied Philadelphia. Customize your personal roster of Freedom Fighters as you and your teammates go from rookie civilians to battle hardened soldiers. Unlock new skills, earn weapon blueprints, rare equipment and combat gear to upgrade.
Resistance mode will launch with 12 missions, with 20 more planned for the first year, and available for free. If you just can't wait until the May 17th release date, you can sign up for the closed beta here.
