First of all, you'll need to install Arkham Revived by Kiwifruit. This is the only way to make MP work, as the servers have been closed a long time ago. What this mod makes is transforming your PC into the server, so the game thinks they are still on. I'll drop below a video on how to install it.



If you struggle to find 2 more players, you can install console commands so the game can be started in only 2. The command is startcountdown . Here is a video on how to install those.

There are achievements where you, unfortunately, need a lot of players. Know thy enemy, Clutch and Predator Paragon require a full lobby, meaning 8 players. There are reports of them working with 7, meaning there is only one Hero instead of 2, but I didn't figure out if they actually work that way. You also have I Like Those odds that theoretically require only 5, four Elites and one Hero. You'll have to find a handful of people to do these achievements.


The rest of the achievements can be done with 3 players, or, if you are using the console commands, with only 2.

There are a few achievements you'll need to grind

Reach max level with the Bane faction in multiplayer





Reach max level with the Joker faction in multiplayer





Reach max overall level in multiplayer





Earn a level of prestige in multiplayer





These are the most annoying achievements, as they require the most time. In order to farm the xp required for them I suggest the following: If done in 3 players, the Hero player basically does nothing, or he can assist the Elites to gain more xp. It is easier for the Bane player to farm xp, as he can use the dart to ping both the Joker player and the Hero to gain additional xp every 10 seconds or so. Use the V1 version, as it has the fastest recharge rate. The Joker player can kill the Hero for the xp.


The Elite players meet at a capture point. One of them captures the point. Immediately after that, the other one goes in the capture area for a split second, as to decap the point. Right after that, the other player gets in to capture the point. You repeat this again, again and again. With a good rhythm, the player who caps the point can earn anywhere between 30k and 60k points per match. At the end of the game, reset the lobby and go again or switch the players around.

Because you are self hosting the server and not actually playing on a official one, things can get a little.... confusing. You can check your progress using ArkhamRevived. I suggest doing this after every game, because you'll need to meet some specific conditions.

The mod, for whatever reason, puts your mp savefile at level 25. Ingame, the progress won't actually show, however it can be easily tracked with ARSH. Check for the gamedata tab and track your xp.


For Bane faction:





For Joker faction:




When you get both factions here, as I stated before, everything must be done IN ONE GO. If you close the game, the progress resets to the values before the session. Don't worry, it will only go back to those values close to 108900, so you won't lose all your progress, but it is still annoying.


You'll get the factions' level achievements faster than the overall multiplayer level one. Don't worry, it is a couple more games for it to also go to 30. When you get both factions close to 108900 xp, the account xp will look something like this:





It is around 400k total xp to get to level 30. Just keep playing after you hit level 30 with both factions, you'll see that after a few games, the progress with register ingame.

Once you hit level 30 on your account, prestige. Those are all the grinding achievements.

One more achievements that needs to be done in a specific way, is this one:

Win a round of each map with each faction in multiplayer





Oddly, after going over 108900 xp, the map wins also stop registering in the files and have to be done in one go. I recommend you do these firstly. As an elite, simply capture all points and keep killing the other player. You should be done in a couple of minutes. If you are playing Hero, just kill the Elites until you win. You can also check if the progress registered using ARSH. It will look something like this:

There are a couple achievements I haven't talked about, Arsenal, Awesome - you need to fully upgrade any weapon to level 9 and Not An Ordinary Criminal - earn 4k xp in a match as an Elite, but these are very simple to do and can be done while you achieve the other ones.

After all this, you'll have earned all MP achievements for Batman Arkham Origins.

I hope you found this guide to be useful.
