For those who played this when it came out, you'll have a few hours worth of fun replaying through some memorable levels. I'd recommend it. However, as the game progresses, it really shows its age. The main issue is the enemy AI. You will repeatedly find yourself being killed by enemies who you cannot see (usually behind five bushes with no muzzle flash). This becomes very frustrating after a while. As many other reviews note, the Sniper Town mission is particularly annoying, as dying is not usually a result of a lack of skill, but rather needing to essentially learn a choreographed routine to progress through the map, which is not very organic. There seems to be around 50-100 active players in multiplayer at any given time (you need to download a third-party patch to access the serverlist - do so at your own risk). The populated servers are usually weird modes, or have weird mods. It might seem like it'll be fun nostalgia but it probably won't be.
