I never built it but i heard that it breaks if you use it alot so maybe not worth it. But you can try making it its good for high rounds
Its ok, but its better to have a zombie shield instead.
But it is fun to fly around with it
on solo, no, takes days to do it. plus it does blow up if you dont let it cool. on co-op go ahead if you wanna try it out, but like i said if you dont let it cool itll blow up and youll have to rebuild it.
its very handy to have on the high rounds when ammo is scarce once youve learned how to use it properly , i had it from round 1 to 35 and never blew up once , never even needed to pap just used jetgun
It's definately worth making if you want to go high round. Experiment with it, if you just hold the trigger down then you aren't using it effectively try just tapping the trigger if it doesn't heat up too much it won't explode. Worth noting aswell is it only cools down if it is in your hands ie the weapon you are holding.
Only if you are going for a high round on solo or co-op, then it is mandatory. It's usually a waste to build it in a pub match because the game can end abruptly due to host migration, and is simply unnecessary because you rarely go 20+ rounds with randoms.
