U3 Beta is now available in HK and Korea Playstation Store. In US, it will be available at 2pm PST.
These are Team Deathmatch videos. The first video is Airstrip map and the second is Chateau.
The airstrip map is exciting but way too small. After the take-off, the game goes to the next section, which is a small airport and have many CQC areas.
The chateau map is a classic Uncharted world. They added nice touch like ‘high five’ at 2:00.
