Grinding for cash in an Assassin’s Creed game has never been so important as it is in Unity. While buying weapons isn’t a huge need, upgrading your armor and purchasing consumables like ammunition is. If you’re interested in making cash in Unity, upgrade the cafe and buy social clubs around town. I spent a couple hours doing all the cafe missions (the last one is a huge pain in the ass) but I went from making 160 livre every 20 minutes to making around 11,000 livre in 20 minutes. It’s totally worth the two hours so that you’ll be able to just have cash rolling in on a consistent basis. I wish I had done it earlier.
