I have played quite a few hours of this now and I can say it is an awesome sequel to Wolfenstein: Enemy Territory and if you are familiar with that game it won't take you long to get the hang of the interface and missions.
My favorite class from W:ET was Field Ops and the Strogg equivalent, the Oppressor, is brutal! He doesn't get to throw down ammo like the Field Ops but he gets portable energy barriers instead.
The beta only has one map, so it doesn't take long to get familiar with the terrain. Judging by this map however, the missions are going to be really fun.
