Hello Choo Choo Engineers!
I've done a fun update to the beta of Choo Choo Survivor 2 (action roguelite where your drive through the zombie apocalypse) and I've added a smaller boss that you can choose to fight near about half way in the map. When you defeat the Relic Keeper you will be given the option to install another auxiliary system on your locomotive (choose one of three presented at random). This will allow you to experience interesting combinations of auxiliary systems on any locomotive you select and I think there will be about 10 auxiliary systems to choose from in the full game.

You can download the game here on Itch or you can join the playtest on Steam. If you like the game then please do wishlist it on Steam.

I've created a new very cool auxiliary system called the lightning rod and it calls down lightning from the sky. You can upgrade it a lot and the ultimate upgrade is that the lightning will stun any zombie (except bosses of course) struck by it for four seconds. Stunned zombies can't move or attack.

I'll be working on another auxiliary system for the beta over the coming days and I'll aim to share that with you soon! Btw, please do give me feedback on how you are liking the game!

Thanks,
GTGD
