If Surviv.io was combined with Battlefield, you'd get Battledudes.io. There are tons of tanks and vehicles and everything on the map is destructible. All guns and player in Battledudes.io behave the same, however if you can influence that behaviour by selecting one or two of the unlockable perks. Perks can increase your weapon damage, health amount, weapons switch speed, weapon reload speed, your running speed and many other stats. This allows you to make many weapon and perk combinations for you own gameplay style!
To communicate with your teammates use the emoji wheel. Summoned by the right mouse click, it allows you to communicate with teammates regardless of your and others language. By playing the game and gaining coins you can unlock and purchase many new emotes.
Battledudes.io includes a leaderboard with daily, weekly and all time statistics. If you create an account to save your XP, progress you can also compete with other in the leaderboards.
In the games show you can purchase new hats and emotes with either the coins currency or the gems currency. Coins are earned by playing the game and gaining XP. Gems can be purchased from the store. Each currency can buy a certain set of items.
