I found this map online. It is a user-made map that is pretty much like Rock 2. There are no instagib forcefields if you run through the other team's respawn, but they are protected by doors. Also sentries in the front up top if they are on the sides are subjected to sniper fire. There isn't a pit of doom coming out of the water either. But the guy did a pretty good job for a Beta. Anyway here's the link.
