Long Grind Multiplayer Achievements via Solo Play (Bioshock 2)

Bioshock 2 multiplayer had the potential to be fun, but it never will be. There isn't a strong player base at all, and most newcomers will be quickly deterred. Half the time you want to play, you won’t be able to find any other people playing. And the times you actually do find others online: there's a good chance most of those people will be toxic players. Of course some of them were nice enough people, but it was my experience that a disproportionate percentage of the people I regularly encountered in “pubs” were either: trolls, keyboard warriors, cheaters, or angry children. Any adult gamer will quickly see it isn't worth his or her time.

Fortunately, most of the grinding achievements that would otherwise require you to endure hours of the painful multiplayer experience can be farmed in private matches, by yourself, quickly and efficiently— even though the achievement descriptions clearly state they must be accomplished in "non-private" matches. It is boring, but you will actually gain XP faster than playing online, without needing to find or deal with other players.

This may be due to a bug, or it may be because the "non-private" qualifiers on the achievement descriptions are actually leftover from the GFWL era, or the console versions. They most likely were originally put there as an attempt to stimulate the online community by forcing people to play match-making. If it is a bug, and you are the type of person who generally wouldn't feel comfortable earning achievements via exploiting bugs: then you will have to decide for yourself if this crosses the line for you.

First thing you are going to want to do is start up multiplayer and start a private match. Set the game type to ADAM Grab. Now play and win one round on each of the maps. All you will need to do is grab the Little Sister and wait for 3 minutes to pass and you will win. This is by far the quickest way. After that, you will have to find a real match (i.e.: a public match) and you will need to play one game (you might need to win it, but I’m not positive), this will cause it to check for achievements and award you:

Man About Town – (Played at least one non-private match on each multiplayer map.)



Aqua Incognita – (Played at least one non-private match on each downloadable content map.)


Territorial – (Won a non-private match in each of the 6 new maps.)



-----------------------------------------

Now for the real grind. You must reach level 50 and “Rebirth” to get all the achievements related to your multiplayer rank. The same method you used for the map achievements is viable here. Pick a small map and play ADAM Grab by yourself. You should get over 1000 ADAM every round, with each round lasting about 4 minutes (including stoppage and loading times). This will net you over 15,000 ADAM an hour and is far-and-away the quickest way to level up your multiplayer rank. This method is effective, but boring; so, I suggest you do this while watching TV or something. Be aware that you will not earn the achievements until you play through a real match and cause the game to check for achievements. Using this method, or a combination of this method and actually playing, you will quickly unlock the following achievements:

Parasite – (Achieved Rank 10.)



Little Moth – (Achieved Rank 20.)



Skin Job – (Achieved Rank 30.)



Choose the Impossible – (Achieved Rank 40.)



Reincarnation – (Used Rebirth to start again!)



-----------------------------------------

Based on some brief experimentation I conducted with my friend, it would appear the other multiplayer achievements that only require a singular action (kill a Big Daddy, capture a Little Sister) will actually need to be accomplished in real public matches.
