How to unlock the Arsenal achievement in Undertow - Definitive Guide
You must level all 4 classes up to Level 3. It takes 2000 points get to level 2, and another 3000 to get to level 3. In total you will need to obtain 20,000 points to fully upgrade all 4 classes.
Easiest thing to do, with your partner, host or join a ranked Conquest game and simply take turns taking over the same control point which in total will net you 325 points each time.
Using this method will take 20-30 minutes. Thanks to DJP519 for the info
set up a ranked conquest game with 400 tickets (not that many needed).
Go to your friends spawn point and keep killing them (more people on the other team the faster you get the kills) you get 250 points per kill so to get the 20,000 points needed you will need 80 kills.
Be carefull not to get to close to the spawn point or you will start to capture it creating a shutout.
Quite simple achievement when you boost it and it will also go towards the upgrade all races to level 3(that can be done in any mode)

But far faster than this swimming around the map taking the spawn points everyone else seems to say ...
Instead of taking over the same control point, which would work. Use all 5 control points. So each player circles the board capturing each control point.
For example player 1 takes over control point 1, while player 2 takes over control point 4. After both players have captured the control points, move on to the next one.
Make sure you are moving in the same direction, as that eliminates any confusion, or chance of accidentally getting a shutout. With this method we were getting 250 points for breaking the capture and another 250 then you take it over. You will have your 20,000 points in less then 15 minutes!
Note: you must have a boosting partner, and make sure your playing on Conquest.

400 tickets.
Now, the player on red team swims over to the blue team base and neutralizes it without capturing it. He then returns to his side and begins to capture point 2 while the blue team member captures his main base. The two then begin to go back and forth capturing these two points easily knocking out the achievement before the tickets expire.
You can do it legit, but it will be much easier with a boosting partner. You must have at least 20,000 points total to upgrade all of the units in one match. Each unit takes a total of 5,000 (Level 2 - 2,000, Level 3 - 3,000). Kills give you points for damage but it may be easier to exchange taking over control points. You receive 125 pts for each control point you fully neutralize by yourself (make dark) and 250 for each control point you take control of by yourself (make your color). Host a Multiplayer Versus Ranked game and set it for 2 players and "No Limit" for the Round Duration and a map you and your friend agree on so your friend can find your game. If you wish you can set the match to Conquest so at the end you can take over all the control points and receive the "Hydropwnage" achievement as well.
