It's basically a strategy game where you build a base as well as defenses, like towers and walls, using the resources you've gathered and once everything's secure, you can then put in your gold stash to start the defending. You'll need to defend your stash from hordes of zombies who will usually attack at night along with other hostile players. You can also build gold mines to generate gold and upgrade your gold stash, which will in turn let you upgrade your towers and walls. You can even spend the cash at the shop to buy better weapons or upgrade your existing ones.Zombs.io may be the more interesting game, as compared to Moomoo.io, namely because it has a zombie- and tower defense-theme.
