This is my first post on the Spiral Knights forums, so don't be too harsh on me...
So we have three in-game packs. Starter Pack, Battle Pack, and the Battle Royale Pack. I suggest a fourth; the Ironclaw Pack.

Ironclaw Pack - $59.95

12,000 Crystal Energy
8 Mist Tanks
4 Heat Amplifiers
5 Krogmo Coin Boosters
3* Handgun: Vertigo Deconstructor
Unique costume helmet: Roarmulus Helm
Unique costume armor: Roarmulus Plating
Commemorative Artifact: Munitions Crate

Vertigo Decontructor – 3.33 bars Normal dmg; 4.5 bars Speed; 4-shot magazine; Damage Bonus vs Construct: High: A powerful Gremlin-created blaster issued to those who braved the Ironclaw Munitions Factory. It may look simple, but it’s got more gears and moving parts than a Mecha Knight!
Roarmulus Helm – A special helmet created with the design of the Roarmulus twin gun puppies in mind. Be careful, stare at it too long and it might shoot you!
Roarmulus Plating – A special set of interlocking armor plating that was created with the design of the Roarmulus twin gun puppies in mind. Be careful, stare at it too long and it might shoot you!
Munitions Crate: Spiral Knights adventuring in the Ironclaw Factory sometimes come across crates packed with gremlin weapons and gear. Some pick these up and keep them as proof that they conquered the Factory. The technology the crates contain is puzzling and confusing, much like the Clockworks themselves.

So it's an upgrade of the Battle Pack, like the Battle Pack is an upgrade of the Starter Pack (sort of). Based on the Ironclaw Munitions Factory, as you can tell, with Roarmulus Twins stuff and an anti-Contruct handgun, etc.
What do you think?
