ActionQuake2 was a hugely popular mod for Quake 2 and for a while it coexisted with Counterstrike. The gameplay was way faster compared to CounterStrike with itsclassic Quake2 movement.
In the end Valve supported CounterStrike whilst ID software did not support mods at all for their platform which in turn sealed the fate for Actionquake2. There was attempts to port it to Quake3, but the gameplay never compared.
Some of the same people were behind Actionquake2 and Counterstrike and there's an argument to be made that AQ2 was the proto CS game.
yeah I even remember playing actionquake2 in maybe 98 or 99 shortly before cs became a thing. tbh I played it maybe twice, because at the time I was playing q2 competitively and actionquake2 seemed more like a novelty. also I might be wrong, but my impression is that actionquake2 never got big in Eastern Europ: since we mostly played at lan cafes, without internet, you were kind of forced into a handful of games. q2, cs, sc. but I could've sworn there was another mod that had the word "urban" in the name. like "urban assault" or someshit.
