Tip 1 Railguns in steamcraft are even more slow, but therefore powerful than in any other game of the sort. Because of this slow fire-rate you really have to consider positioning as one of the key aspects to playing a rail craft.

Tip 1 Something cool that I found is that by pressing the f key while in motion, it can spring you forwards and upwards a decent way, this allowing oneself to vault up large mountains not scaleable by just wheels alone.

Tip 3 A good combo (if you can call it that) is shooting off a few wheels, then waiting for the bot to flip itself, with the way most people build their crafts, the core is peeking out on the bottom, just waiting for a good rail shot

I hope that whomever reads this appreciates this guide and that it helps.
