Serious Sam HD: The Second Encounter is getting another dose of downloadable content, set to hit on May 15. The "Legend of the Beast" DLC packs in three campaign missions, three survival mode maps, and three versus mode maps, for $4.99.
In addition, SSHD2's versus and survivor multiplayer modes will be switching to a F2P model starting May 15. Those modes include Capture the Flag, Deathmatch, Team Deathmatch, Instant Kill, Last Man Standing, My Burden, Survival, and Team Survival. The announcement didn't mention how this model will be monetized, but Croteam has offered free multiplayer weekends in the past.
"Our team is very excited to extend the world of the classic Serious Sam: The Second Encounter and we think the fans will really enjoy the new areas and scenarios we've put into Legend of the Beast," said Croteam's Davor Hunski in the announcement.
