Capcom has unveiled new details of the upcoming PC version of Resident Evil 6, confirming that it will contain a new and exclusive mode, The Mercenaries: No Mercy. This new mode will add additional enemies onto the screen, but also the opportunity for players to use their skills to rack up high combo scores.

Capcom has also confirmed that PC players will be receiving access to previous features added to consoles post-release including the Ada Wong campaign, in-game camera tuning and access to ResidentEvil.net. A free benchmark test will be made available in February as well for those needing to flex their specs.

Alongside the PC details, console players of Resident Evil 6 will be able to further expand their gameplay experience with the release of a fourth additional mode, Siege. The new mode will be available sometime in March for PlayStation 3 and Xbox 360.

Siege sees a lone AI-controlled rookie BSAA agent in trouble and in need of help. Players will split into two teams with one assuming control of enemy creatures who are trying to take down the rookie, while the other team selects playable characters from the main game and must keep him alive.

All four post launch game add on modes – Survivors, Predator, Onslaught and Siege – will be made available for PC owners to download and purchase shortly after March 22, with any future title updates for the console version also being made available free of charge for PC owners.

Resident Evil 6 for PC will be available on March 22nd.
