[RKD] Arsenal
Weapons and gadgets of every epoch – from the short bow to the railgun, plus grenades, jetpack, grappling gun and mounted guns. The server decides every hit; block damage is off by default.
Overview
Beta – test server – Test build for the beta test server. Features and values may still change before the final release; please report bugs.
[RKD] Arsenal brings weapons and equipment from seven epochs: Stone Age, Antiquity, Middle Ages, Gunpowder, Industrial, Modern and Future – each with hand weapons and heavy mounts (guns) you set up, man and load. The mod is made for the planned game-in-the-game [RKD] Command, but works just as well in normal survival (can be switched off).
The client only reports “trigger pressed/released” – every hit is computed on the server. Weapon stats are data files inside the mod and can be changed with a datapack. Block damage is off by default (except in Command arenas), and so is friendly fire.
Seven epochs
Short, composite and long bow, crossbows, flintlock pistol, musket, revolver, sniper rifle, SMG, assault rifle, rocket launcher, guided missile launcher – up to the future's laser, plasma and railgun weapons.
Mounts
Ballista, catapult, trebuchet, ship cannon, machine guns, autocannon and tank cannon, rocket pod, anti-air and future guns: set up, man, load – or switch to automatic.
Ammo types
One item per calibre, the type is stored in the item: standard, armour-piercing, hollow point, incendiary, explosive, tracer, slug; shells AP/HE/HEAT; fire, poison, explosive and piercing arrows.
Grenades
Frag, sticky, impact, flashbang (walls protect you, looking away helps), smoke, incendiary, implosion (pulls everything together), EMP (disables jetpacks and energy weapons), C4 with detonator and land mine.
Gadgets
Jetpack with fuel, grappling gun to pull or swing, jump boots and jump charm (double jump), medkit, adrenaline syringe, binoculars to mark targets for your team.
Aiming & lock-on
Scope with zoom levels, guided missiles lock on after 1.5 s, the railgun charges and pierces targets. Hit markers, damage numbers and tracers (all optional).
Fair in multiplayer
Teams, the PvP setting and friendly fire are respected; weapons everywhere, only in arenas or only in creative – every weapon family can be disabled on its own.
Loadouts
With the [RKD] Core preset library you remember which Arsenal items sit in which slot and sort them back; operators can hand out loadouts directly.
