As far as I know, BrokenLens is available in Bedrock Edition as well as in Java Edition. It should be possible for you to play on Java.
MobWars current isn't capable to play on Java, As well as KrazyKarts. You may need a party to join the game, Although. It may not work quite well.
There’s a way to bypass this, for both games. (But KrAzYKarts I do not recommend) Just be invited to a party and have the party leader join the game.
In truth, if one makes a party I have invited someone from Java to play mobwars, it will be horrible for him, he will have too much lag that you can hardly run and walk.
Idk, but my sister who plays in java played mobwars thanks to a party and was doing horrible, in the end she had to leave the server
Ya I don't lag.. I played with ya... but the shop is broken for Java and everything will look like as Steve or Alex when you play MW....
