Jupiter Hell 0.9.0 - Masters!

Jupiter Hell 0.9.0 - Masters!

Hell, it's about time! Our most significant update yet, Jupiter Hell 0.9.0 -- a.k.a. "Masters" (of Doom? :P) -- is out, and with it, 15 (fifteen!) Master traits have been added, each bringing a unique playstyle! Read all about it below!

But before we get to the meat, this is our most important release up to date and we want to reach with it as many people as possible! We've set the price -20% off, and would be honored if you'd help us spread the news among friends, communities and your favorite streamers! Only YOU can really help us out with this quest!

Also, if you want to discuss master builds, be sure to join our Discord Server :)

Masters!

Fifteen Master traits have been added, five per class. Some of them are generic, some of them tailored toward a particular weapon group. All of these have 3 trait levels that can be picked -- one each at level 7, 10 and 13. Contrary to prior updates, Master traits have relatively few requirements (3 or 4 traits), and do not block any other traits, for maximum build flexibility.

Marine Masters

  • Onslaught - once you spool up your chain-fire weapon (see below), you can move while firing and increasing spool-up!
  • Bulletstorm - adds 1 more shot per action to SMGs and pistols, and reduces their ammo consumption
  • Army of Darkness - designed with Shotguns in mind, this is a generic trait that converts the Slash weapon damage type to Pierce, and maximizes their effective range
  • Vampyre - Health regeneration on melee kills
  • Survivor - generalist trait makes you harder to kill and provides limited regeneration capabilities

Scout Masters

  • Sniper - for use with any rifle, increases ranges and provides a bonus to critical chance which scales with range to target
  • Gun Kata - fan favorite -- automatically shoots both your pistols at different targets as you dance between enemies
  • Gunrunner - reload weapons on move and reduces their fire time for the turn after a move, leading to a run and gun playstyle
  • Assassinate - Scout's flashy melee master -- phaseshift right behind the enemy to deliver a fatal blow
  • Ghost - for the sneaky among us, significantly reduces stealth costs and detects enemies before you see them

Technician Masters

  • Entrenchment - hold position and start spewing bullets - automatic hunker and damage reduction when firing while remaining stationary
  • Sharpshooter - for the pistol fans: increased ranges and damage bonus which scales with range to target
  • Fireangel - when you want to see the world burn. Shrug off explosions and proc fire effects
  • Blademaster - Tech's melee master -- wield two blades at the same time for more damage!
  • Wizard - smoke screen on cooldown, buff to hacked enemies and bot summoning

Apart from that, some of the existing non-master traits have been changed or removed, and a new Eagle Eye trait is present in Scout.

Masters obviously shake up the game a lot, and we tried to compensate balance for it (see below), but generally we kept most of the traits on the overpowered side -- expect more balancing in future updates :P

New Uncommon Weapons

To provide more early-game variety and fill up some gaps in weapon types vs available ammo, we added 6 new weapons that are alternatives to current common weapons:

  • 9mm combat pistol
  • .44 long revolver
  • 7.62 sidearm
  • 7.62 assault SMG
  • 7.62 sniper rifle
  • CRI plasma cannon

All of the above have ADV variants (which now show their tier in the name, i.e. AV1, AV2 and AV3), and are sometimes carried by regular humanoid enemies.

Chaingun Spool-up

Chaingun has changed! To give the chaingun its own niche among other similar weapons, chaingun now ramps up to its full damage potential after two turns of uninterrupted firing, represented by audio and visual effects, and a Spool-up status effect. Pick Marine's Onslaught master trait if you want to move while mowing down enemies!

Improved Animations

Speaking of the chaingun animation, we've also made a general pass on animations in the game - the player's body now rotates separately from the legs when firing and aiming, movement is smoothed out, rotating weapons actually rotate, and other miscellaneous animations were fixed.

UI Improvements

Several minor UI improvements have been made -- health bars now show what damage was done since the last turn, required traits in trait descriptions are highlighted red or green depending on whether or not the requirements are already met, and weapon statistics have been made more compact, and now include explicit weapon-group information.

Major Balance Changes

The inclusion of Master traits caused us to take a significant pass at game balance. In general, we made early-game a bit easier (especially on Medium), and significantly buffed all late game enemies to offset the power of Master traits. Also, there are more enemies in general post-Europa (scaling with difficulty).

Oh, and remember that UV accuracy bonus for enemies? It wasn't working correctly; we've now fixed it. Expect a lot more pain on Ultraviolence ;)

Plethora of Bugfixes

Last (but certainly not least), we fixed plenty of bugs, and we eagerly anticipate fixing the ones that will inevitably popup in this release with the amount of added mechanics :P.

Synopsis

Jupiter Hell is a roguelike set in a 90's flavored sci-fi universe. Set on the moons of Jupiter, the game pits a lone space marine against overwhelming demonic forces. Rip and tear zombies, demons and unmentionable monstrosities, using classic weaponry such as shotguns, chainguns, railguns and the trusty chainsaw. All to the shine of CRT monitors and the tune of heavy metal!

Dive deep into a true form of the 30 year old roguelike game genre that has resurged in popularity. Experience turn-based, grid-based permadeath and fully procedural levels, all in glorious 3D visuals. Get ready for the spiritual successor to DoomRL, the parody roguelike that years ago streamlined the traditional format and popularised a new wave of accessible roguelikes.
