Generals.io is a 2D environment-based strategy game that focuses on the best parts of simple io games while still keeping the competitive feel of strategy games.
How to play
There are eight people in each game, but it's "every man for himself" as you move forward. There can only be one number one, and that's you. You should fully defend your castle by improving the blocks around it. This will make it harder for attackers to get to your castle. Keep in mind that you need to prepare your troops for both defense and offense. Just sitting there like a turtle and waiting for strikes is not the best plan!
Have fun and good luck!
