Tom Clancy's EndWar Online will launch its first technical testing this week. Ubisoft is calling this test "Tech Assault," and will be lifting the veil on it this Thursday, February 27. It will run through the weekend.
The beta will let you play as the European Federation Enforcer Corps or the Russian Spetsnaz Guard. You can register for the test through the official site. This is not to be confused with the closed beta, which Ubisoft is treating as distinct from the "technical test." The beta will be coming sometime later, but signing up for this phase of testing will put you in the pool for it too.
