You may have played the prevous Lockdown maps, now there is Lockdown 2.Public Beta 1 includes some bug fixes of the map "Lockdown 5 player" and that's it. I plan for Lockdown 2 to include upgrades in future versions. Imagine having the ability to Lockdown all the ships before they reach the shuttle in this 5 player map.
