ya, its more similar to CS then BF. and its very realistic, limited HUD and real bullet damage.
i play public, there are lots of good, dedicated servers for it so far. they added a bunch of features to the new one, so dont let the minimalist feel of the OG turn you away, although its still not up there with CoD and BF as far unlocks and maps go.
still highly recommended, and i think its on sale right now thru Steam for 9.99
