What do Mechs and Jetpacks have in common? They're both in this pack! Other than that, hmmmmm.... They're both lots of fun..? Yes they are! They both can be driven around? Yep. Flown/driven, sure. They both have pixels. YES they do! Wow, these things are more similar than I thought.
Get all of these particular items from your local armorer. Yes. they've been going to Advanced Armorer School, obtained their Diploma Of Advanced Armorer-Type Things IV. Well, some of them have, good luck with yours!
Mech
Lots of hit points
Jumps like it's nobody's business
Has a handy minigun on its roof
Runs very fast
Swims very fast
Repairable with redstone and/or iron ingots
Demolition Mech
Bashes its way through just about anything, great for mining or destroying your enemy's base.
Sorta slow
Repairable with redstone and/or iron ingots
Mines all the new blocks! The armorers have been upgrading their mad skillz and have added the ability to mine netherrack, quartz ore, tuff, deepslate and blackstone. And, best of all, made it flame/lava proof!
Jetpack
A pack with a jet on it which enables the user to fly. Crazy, man.
Drops a jetpack when you 'kill' it (handy when you want to pack it away).
Look up to fly up, down to fly down, you know the drill!
