Infinity has a lot of huge swords and guns that are often used one handed. What gives them this property? Is it teseum, gyrostabilization or nano molecular muscular enhancements in even the light Armored forces? Something else? Heavily Armored forces and Wulvers can use all of the above but I’m curious about the rest! Thanks for pointing me to lore in advance.
In general Heavy Infantry units are powered units and the fiber muscles add to the users strength, many Haqquislam special units are bioengineered and altered from normal humans now advanced material and enhanced software are involved to accommodate to this, for example while I am not sure it is written anymore but PanOceania troops have ballistic computer software in their comlogs to correct their aiming on the fly.
Infinity weapons are likely lighter than our own too, with 180 years of material science, in addition to recoil dampening technologies. Many times the poses are not intend to show them using their weapon in one hand either, merely holding them. Swords in particular are already quite light, with even great big zweihanders rarely being more than 2-4kg, often less than a modern assault rifle. For Ariadnans it's mostly just day they're super hench after all that frontier living.
The real reason is that CB thinks that holding one gun in the air while holding a pistol or sword looks cooler than a semi-realistic firing pose.
Ok, the above answers were realistic. I have played Sedition Wars which could have been a forerunner to infinity with cubes and TAGs. I have played Traveller and other iterations like 2300. In all of the games that I play I look for the futuristic concepts of reality. Infinity has the (Warhammer word for person surrounding electronic data sphere) “noosphere” concept that make VR a primitive tv camera. None of these things can magically make the battlefield change except in Aristeia! The swords better have momentum or the penetration is poor, the guns should at least have what DARPA has researched: curving bullets, etc. Tanks are obsolete with TAGS. Got it. There are two formats for war at present in the reality of war. The guerilla, asymmetric type and the all out onslaught. I’m old enough to have trained for the latter in my army time. Although I see references to the massive battle types, I believe that infinity remains a tabletop skirmish game similar to the guerilla type but with no asymmetric means. This is a bug I had with Warhammer until they brought out genuine rules for asymmetric battles, objectives. Age of Sigmar started thus with as little as one unit on one side vs an army, objective met wins. Unfortunately the audience wanted FairPlay even odds skirmish, so I got to explore but little. See any infinity rules out there that simulate asymmetric war or onslaught battles?
