Shell Spinner

Real life examples: Typhoon, Megabyte, Ziggo

In game examples: None (DSL: Grog, The Vengeful)

Offspring of the classic horizontal spinner.

Shell spinners features one spinning shell (a cylinder generally closed at the top) surrounding the chassis. Several weapons are when attached to the shell. This protects the bot, as well as creating a powerful weapon to defeat other bots. Usually in these bots, chassis armor is weak, because most enemies will only be able to hit you when your shell has been knocked off, at which time your pretty much screwed anyway.

The DSL pack is the best way to create shell spinners.

Examples include Scrap Daddy's BBEANS4 entry, Iron Spaghetti

(flail shell spinners are pretty much uncommon, that said)
