Brutal.io vs Zombs.io
Brutal.io
Brutal.io , developed by the very people behind Wings.io, is a competitive PvP game where you get to play as a cell of sorts, much like Agar.io, but with a spiky flail to whack other players with. Like all IO games, Brutal.io is very easy to learn but can be hard to master. Similar to Agar.io as well, you will need to gobble up food fragments scattered around the place to grow your main bulk. The arena you'll do battle in is unique too. It has walls you can take cover behind, and there's even a walled-up area in the middle for smaller cells to hide when escaping from larger cells.Despite the comparison with Agar.io, Brutal.io is not a direct copy of the game. In fact, it builds on what makes the former game so challenging and hence, addictive to play, while subsequently created something that looks and feels different. That being said, Brutal.io is still a game that fans of Agar.io, or any IO games really, would really enjoy.
Zombs.io
Zombs.io is in some way a more in-depth version of Moomoo.io. 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.
