A satisfying tactical shooter.
The graphics do look decent for a game that's 3 years old now, and it still stands: environments are detailed and can actually give a spook in some of the more hectic missions. This amount of detail adds a depth of realism to SWAT 4.
The career mode is a great challenge to both old-timers and newcomers as well. The missions can be played through either Easy, Normal, Hard, or the highest mode, Veteran. The missions are also completely random; you will never know who you're going to meet eye-to-eye with on missions, as the generator always place varied NPCs into the missions, giving it a variety, and making sure no mission always plays out the same way twice.
However, the squad AI is rather glitchy, They sometimes do not follow orders correctly, and sometimes completely freeze when multiple anomalies happen at the same time. This can be overlooked, as it usually is not a problem and can be resolved with a simple "Fall in" command. There are also enough weapons to sate your tactical needs, but it still falls short of the larger variety of weapons that most FPS gamers are used to seeing in other games. Again, this can be overlooked, if not with some difficulty.
The multiplayer is also quite fun to play, and also incorporates a co-op game type which allows players to tackle missions with 5 players total, as well as Barricaded Suspects, VIP Escort, and Rapid Deployment. This allows for plenty of fun and hectic scenarios with plenty of enjoyment involved.
All in all, SWAT 4 is a solid and dedicated tactical shooter, with plenty to offer to everyone that's played an FPS before. It is a fun and tense FPS with plenty of variety and modes for great replay value.
