It was a decent, but overrated game that is now rapidly fading from popularity. It has no multiplayer and no mods. This forum section will soon be utterly dead.
That's complete opinion. Bioshock was actually a very popular, and was rated by IGN an average of 9.6 between Xbox 360, Playstation 3, and PC.
Also, Bioshock 2 will feature a Multiplayer mode, and there has been some speculation concerning some of the game modes:
According to reports, the new Game Informer magazine with the first bits of information on BioShock 2 includes a few details on BioShock 2's multiplayer mode. No hard facts on the multiplayer in BioShock 2 have hit the internet just yet, but David Hinkle at Joystiq has a few ideas for BioShock 2 multiplayer modes we can't argue with:
Big Daddy: This one is a given, with one player taking on the role of Big Daddy, scoring points with each kill. The remaining players must work together (and against each other) to take him down, with the player that dealt the killing blow taking over the role of Big Daddy in the next round.
Splice and Dice: This mode is team-based, and features one side of melee weapon-wielding Splicers who are allowed one Plasmid power. The opposing side is composed of plain old humans. With guns.
Team Slayer: It's UNSC Spartans vs. the Covenant aliens in this fight to the death. Players fight until one side reaches 50 points.
Little Sister Convoy: One team is tasked with escorting a Little Sister from Point A to Point B. While transporting her, the opposing team must take down the convoy and nab the Little Sister for themselves.
I agree with Cyber-Raptor.
I just got the game a few weeks ago and I am not too crazy about it. Yeah, its a good game, but it gets old. About 30 crazy people with bunny masks on come at you with revolvers and wrenches, then a giant in a scuba suit stabs you with a giant drill. After that the little sister runs into a hole in the wall. The thing that bugs me the most about the game is the character design and models. They are all to animated looking. The proportions look really tacky, and it doesnt "add to the creepy effect of the game" if that is what 2k was going for. It just makes everybody look like they are right out of a Kingdom Hearts game, just with blood skinned on them. Other than the character designs, the effects are great. Not as good as Crysis, in my opinon, but they are still great. Maybe when Bioshock 2 comes out, this section will get some potential revival.
