Croteam's HD revamp of Serious Sam: The Second Encounter - due next month - will gain extra multiplayer modes.
Those are Survival, Co-op, Versus and Team modes. Co-op isn't new, of course, but a coin-op-style drop-in mode is. A bonkers 16 people can team-up against the AI, too.
Survival, meanwhile, does as the name suggests, and Beast Hunt and My Burden are the competitive pursuits. The Team modes encompass Team Deathmatch, Capture the Flag and Last Man Standing.
There are new maps as well as Steam leaderboards to climb and Steam achievements to earn.
Serious Sam HD: The Second Encounter also welcomes a Sniper Rifle, Flamethrower and Chainsaw, plus new enemies to use them on and new secret areas to find.
Note, however, that these appear to be PC features - a platform that routinely allows more people to play online together than on console. We'll try to find out more about the Xbox 360 version.
The HD revamp of The First Encounter was released in November on PC and a month-and-a-half later on Xbox 360. Let's hope the additional revamp-extras make a PC purchase more essential this time around.
