My bro Saladin told me many crescent moons ago to play this game. It was an excellent recommendation and ever since I use Saladin cabs to get around town.
The game is old and a little slow responding but this is only downside. The game has so many funny part. My favourite is dodging attacks and watching enemy team kills chasing me. It is the bomb!
When friendly fire on you may have many team kills. All accidents. Some admins will kick everyone like idiot but in the main most people understand the game. Some idiot people will get cheap shot on team mates or keep killing team. This leads to all out free for all war sometime. Still funny.
Game has many class to choose and plenty of map to play. Game is complete mayhem when you have at least five on each team. Not too hard finding at least one semi active server despite age of mod. Game cost no dollar.
