Game designer Josh Hamrick talks about BlackSite: Area 51's multiplayer in his blog post:
"We have eight maps in BlackSite that are pulled from key locations in our single player campaign. Almost all the maps were either hand made or at least hand polished by our amazingly talented multiplayer lead Tom Bonner and designer Harold Handlin."
"BlackSite has four multiplayer game modes. Three of the four are standards that we have all come to expect in any multiplayer FPS: Deathmatch, Team Deathmatch and Capture the Flag. We also have a unique multiplayer experience called Abduction. Deathmatch and Team Deathmatch are classics and as long as the game systems are all working well together they make for great time in almost any FPS. I can assure you that BlackSite is no exception and these modes play great! Abduction is also a stupid amount of fun and we know that there will be large groups of people that will only ever play Abduction. The scoring system makes for a really competitive game and simple changes such as max score and the map size really change the feel of it. There are a large group of Midway Austin employees that swear that the biggest maps are the only way to play Abduction while another group fights for the right of the small maps!"
