CoC like sport with defence gameplay?

So i used to play Cloud Raiders however now i realised that the video games is closed down. They’d this type of defence sport play that doesn't exist in CoC. Mainly you’ll protection in opposition to a boss or waves of very trong troops. It goes like this: or this Is there any video games with this type of gameplay? And eventually, i do know this query is a bit unrealistic bit is there anyway to convey again an offline model of a closed sport or am i able to rebuild the sport if there's the sourcecode someplace? Thanks.
