I used this mod since a couple years now. In my eyes, these are the highlights: -Tons of replayability added -Missing/ planned content added back in the game, games feel more complete and polished -More coherent mission listing and single-player experience -Multiplayer fully working on this mod, flawlessly in most cases. -Game get slightly harder , more challenging. (penalties , AI overhaul , more impredictability) -The mod keep it real with the base game, nothing feels out of place -The 2 extra maps are a welcome addition. -Huge number of quality of life improvements The mod description is accurate. I think the SEF experience is actually the best way to play Swat 4 nowadays. This mod have almost no downside. For what it adds to the base game, I say take it 100 % of the time, especially if you have already finished the game. I give this mod a overall rating of 95/100.
