Ok, soldier surely is no big discovery of mine. This game already has a big fanatic community. And this community exists, because Soldat is stable, nicely and originally designed, and incredible fun to play. With 18 different weapons, 7 game modes and 42 maps there's no chance of being bored in any way...
Soldat really is a fine alternative to FPS-multiplayer-shooters. Being excellently supported, you will always find a server with some soldiers playing on of the different gamemodes.
The graphics are good for this type of game, although some parts could be improved, the overall impression is a homogeneous one. I like very much the ragdoll-style of animation of your soldier.
I can think of no other action multiplayer game, which is NOT a FPS, which is so much fun and so regularly played like Soldat. A true "phenomenon" in the freeware-section. Let's hope that it stays free...
