    While searching for a good method for farming those credits I felt like... I will never get this.

    Endless Mode needs so much time.. farming level 1 too and getting s+ ranks is just too hard for me.

    After trying this and that I found a good midway.

    Just beat level 5-2 with your ai‘s. Getting a rank B will give you around 350 - 450 credits and it just takes around 4:20 min‘s.

    Getting good ranks -> credits in the other maps is way harder.

    From the main menu, go to COLLECTIONS then EX OPTIONS. Purchase AI PARTNERS as early as you can, then set it to maximum.

    In CAMPAIGN, go to ZONE 1 STAGE 1 and you can let the AI complete the stage to earn credits for you. You just need to press Y each time the stage is complete to restart it. Use credits to purchase all EX OPTIONS for achievement.

    If you are not consistently getting a rank of B or better, go back to ANDROID SELECT and re-select a character. You can do this to randomize the AI selections until you get a better team.

    TheOnlyMattoI love a good AFK strategy. Pick one of the bad characters, like aubergine, and just let yourself get knocked out. Hit cn_Y and go again. By picking a bad character you have better odds of a good team. Ty, thumbs up. (rubber band turbo controller thats plugged in and you can farm over night)

    I also got 15,000 kills without having to shoot, apparently your team mates kills count for you.

    The EX Options can be found in the collections tab of the main menu.

    To unlock all of the EX you will need 23.500 credits.

    There is no easy way to get a lot of credits. Credit drop depends on your score and on if you have beaten/improved your previous rank.
    Infinity Drive seems to have a good drop rate at higher levels.
