Usually, for infantrymen and power armor, this is self-explanatory… or at least easily ruled on. No one expects an infantryman or a power armor to dual-wield bazookas while carrying four spares on their back. For larger platforms such as mecha and starships, however, it becomes more nebulous. The rule we offer is: a maximum of 8 On-Tier Weapons (OTWs) and a max of 2 Tier-Equivalent Weapon Groups (TEWGs).
A Tier-Equivalent Weapon Group (TEWG) is a group of lower-tier weapons whose combined “purpose” (read: damage output) is equal to their host platform's tier. Consider, for instance, a Tier 10 (Light Starship) vessel like the Yui 7-class Scout. The following are just a handful of the combinations that would count as a single TEWG for the Yui 7:
A gun capable of firing Tier 10 (Light Anti-Starship) 300mm solid mass driver rounds, however, would not be considered a TEWG for the Yui 7-class Scout. It would instead be considered an OTW, due to the gun's ammunition being the same tier as the Yui 7.
The following are additional notes and errata for the rules described above.
Let's say that I'm an evil Mishhuvurthyar villain recently freed from imprisonment on Luna Bianca who has decided to create an 80-meter-tall Giant Robot Dinosaur so that I can wreak chaos, havoc, destruction, and despair upon the unsuspecting residents of Kyoto City.
Since I want to have two Laser Eyes of Destruction™, I take those 8 Tier 10 (Light Anti-Starship) weapons and convert them into…
…and then convert those four weapons into:
So, in the case of my giant robot dinosaur with laser eyes, it can kill with a glare.
But wait, I wanted it to breathe fire too! And I want my fire breath to cause more damage than my laser eyes. Back to the drawing board: I divide 1 of those Tier 12 (Heavy Anti-Starship) weapons back into 2 Tier 11 (Medium Anti-Starship) weapons. Those two will actually be my laser eyes. The bigger one is my fire breath. So, now, my loadout looks like:
Then I remember that I’ve forgotten about the 2 Tier-Equivalent Weapon Groups. Back to the drawing board one more time: I take those 2 Tier-Equivalent Weapon Groups and - since they're each “worth” a Tier 10 (Light Anti-Starship) weapon - split them into:
These launchers, located on the flanks of my Giant Robot Dinosaur, will be my point-defense against any pesky fighter jets the inhabitants of Kyoto City send to fight me. So, now my loadout looks like this…
…and there we go. My Godzilla impersonator is armed and ready to smash, stomp, burn, rip, and tear Kyoto City into rubble! MUAHAHAHAHA!
