That's the date and time marking the full release of J-Jump Arena! The update will include:

• Reworked controls
• New maps in an entirely new biome - Postapocalypse
• New weapons
• And more...

Matches now play out smoother!

The following changes were made to ensure a better gameplay experience:

• If every player performs a jumping action or does nothing, the turn starts playing out noticeably faster. This is more noticeable in game modes that don't feature weapons.

• The time of all weapons that explode in X seconds has been shortened by around 30% on average.

"Wardrobe" added to the game!

There is now a "Wardrobe" icon in the top-left corner of the "Edit Character" screen. The "Wardrobe" allows players to save/load up to 8 different outfits.

Customization items

• Added a male version of the robe, unlocked by playing on the Swamp maps.

• Added a version of the witch/wizard hat with short hair.

• Added a version of the cowboy hat with ponytail hair.

• Added a version of the Santa hat with ponytail hair.

• Added a pink colour variation to Santa-themed outfit parts.

Important connection bug fixed

On rare occasions, a player would host a private match and others would be unable to connect to the room. This was an uncommon occurrence, but it's finally been dealt with.

Update incoming!

Let's celebrate it by playing together this friday, in Public Multiplayer!

30th May 2025

• Added 5 new Win Poses for VIP DLC owners.
• Added 2 new Idle Poses available from the start.
• "Pants" option available in Settings now adds 3D modeled pants, not just a texture slapped on the character.
• The 3D model has been retouched and re-rigged to improve deformation, fixing issues like the neck bone affecting chin deformation.
• Fixed various minor instances of clipping issues of the 3D character model.

It's Time to Introduce 3 New Weapons!

• Kinetic Blaster

  A gun that fires an energy bullet that doesn’t deal a whole lot of damage, but pushes the victim with force! Good for pushing out of the map those poor sods who are too busy throwing grenades instead of finding a safer spot.

• Quacknator 9001

  As deadly as it is adorable! This rubber duckling either grows or explodes at the end of each turn. The bigger it gets, the higher the chance it’ll go BOOM! Dangerous on smaller maps. Oh, and it floats on water, too!

• Super Revolver

  Extremely rare and works just like a regular revolver with one exception — it does double the damage! Stay alert if someone nearby manages to get their hands on it. And if you’re the lucky one, don’t bloody waste it.

To the Moon!

New Unlockables!

Bug Fixes & Balance Changes

• Underwater explosions now deal 75% of their normal damage (was 50% before).
• Mines have bigger trigger areas now, but they’re harder to see (more transparent).
• Zap Bombs do an extra +5 damage when they explode underwater.
• Zap Bombs, Sonic Bombs, and Unholy Bombs can’t be damaged by explosions or fire anymore.
• Dynamite used to have a 3% chance of not exploding after lighting the fuse, but I’ve removed that feature because it was more confusing than fun.
• If you're on fire and hit by something freezing, the fire goes out, but you won’t freeze. Before, freezing objects did nothing if you were burning.
• Frost explosions now put out fires.
• Bots are a little smarter now - they won’t jump off the map as much.
• Fixed a bug where weapon bubbles would sometimes appear right on top of the player.

Tutorial is now available!

Other fixes & changes:

• Fixed a bug where, for example, if a player had only one empty weapon slot and jumped into the pickup bubble with two weapons, the bubble wouldn't despawn.
• Added a sound effect for when the player reaches a checkpoint.
• The radius of bullet colliders has been slightly increased.
• The outline parameter of characters' skin material has been adjusted, resulting in fewer visual glitches.
• Fixed an issue in the settings where the screen resolution change wouldn’t be updated when returning to the settings menu after applying the changes.

Say hello to a brand new 1 vs 1 Duel mode!

Let's sum up the update in a few bullet points:

• The new mode is available only when 2 players are in the game.
• For public games, if it's just 2 people in the lobby, 1 vs 1 Duel will always be one of the three match options available to vote on.
• 5 new maps have been added for this specific mode. They are symmetrical.
• The same weapons will spawn on both sides of the maps symmetrically.
• Every time your opponent is eliminated, you get +1 score.
• After each elimination, a new round will begin - both players will respawn and the whole stage will reset.
• The first player to gain score of 3 wins the match. This can be altered in private games.
• There is no turn limit. Match goes on until one of the players reaches the required score to win.

4 new weapons make their debut!

• Unholy Bomb

  {STEAM_CLAN_IMAGE}/42669711/7fd2a6ed36cf6d26612485c63f3c3fa11365881a.png A rare bomb with devastating effects! Not only it takes away 50% of player's remaining HP, but it also applies a fog curse, causing the player to have their vision greatly obscured!

• Mortar

  {STEAM_CLAN_IMAGE}/42669711/a5c0743a8f33f32b2436ad9e8f1cb7d89b1a1fe4.png Mortar allows you to easily choose a place on the map, to which you will send 4 explosive devices raining down form the sky!

• Powder Keg

  {STEAM_CLAN_IMAGE}/42669711/6de06aa01e738eac20c5947f1118b9c24a88bc2b.png When you choose this weapon, you'll jump like you normally would, with one exception! You'll leave behind a powder keg that explodes after several seconds.

• Teleporter

  {STEAM_CLAN_IMAGE}/42669711/7ff03f858463c5dd1046985b6c343a2fa35cd4ad.png A device that allows you to pick any place on the map, to which you'll smoothly teleport yourself to! Whether you want to get away, or reach a difficult place to get, teleporter has you covered!

Welcome to hell!

Widescreen resolutions are now fixed!

3 new weapons make their debut in J-Jump Arena!!

• Frostcore When thrown, it explodes on impact freezing nearby players for 2 following turns! The tricky part is, players that are frozen are unable to move but receive 90% less damage.
• Frostmine Similar to Landmine, except it freezes players just like Frostcore does!
• Incendiator It is very much like Shotgun - it also shoots 6 bullets, except these put players on fire! Careful though as it's even less accurate than Shotgun is!

Snowland maps!

Other updates...

Balance changes:

Other improvements:

5 new maps have been added to the game:

• 1 "medium" canyon map
• 1 "medium" forest map

List of other fixes and tweaks:

• Increased data send rate to provide a smoother multiplayer experience.
• When it comes to "Disappearing Platforms", third person view is now default camera view when aiming to jump. You can use left shift for first person view.
• Slightly increased the explosion radius and damage of Bazooka.
• Fixed the animation of fire as it sometimes wasn't working properly.
• Fixed an issue where if a player was eliminated due to a fire, they'd respawn and still have the "on fire" animation.
• The protection bubble that's put on a player after respawning now protects them from fire.
• Adjusted the color or protection bubble to be a bit more vibrant to increase its visibility.
• Fixed an issue where players would sometimes respawn one atop of another.
• Changed the trail color of Super Grenade to red.

Deathmatch Balance Fix

Jumping Controls Update

4 new weapons have been added to the game!

• Zap Bomb Explodes with electricity! As long as the player is within the explosion radius it does the same damage, no matter the distance to explosion. If it explodes underwater, it only affects the players who are standing in the water, but explosion radius is much bigger!
• Cluster Grenade Explodes creating four more smaller explosives which detonate soon after. Doesn't do as much damage as a standard grenade, but covers more area.
• Sonic Bomb While it doesn't do a lot of damage, it pushes the players away with a great force!
• Super Grenade A weapon that's rare to spawn! Works like a standard grenade, except it explodes sooner and is MUCH more deadly!

CHANGELOG:

• "Deathmatch" mode! It's a pretty common mode for a lot of games, but for those who don't know what it is about: It's a weapon mode like Last Man Standing, except that when you get eliminated you respawn and keep playing. Every player you eliminate adds +1 to your score, while if you accidentally eliminate yourself you lose -1 from your own score. The mode lasts 25 turns - this might be adjusted in future, depending on feedback. I've added Deathmatch, because Last Man Standing was by far the most popular mode, and it's really frustrating when you play with a group of friends and you have to wait after being eliminated early on.
• Bots added to Public Games. I've always been against adding bots to public games, but let's face it - playing 1 on 1 is boring most of the times. That's why from now on, buts will be added to the game, but only to ensure there's at least 4 characters playing at minimum. This means that if it's just two real players playing, they will play along 2 bots. For 3 players, only 1 bot will be added. From 4 players and above, no bots will be added to the match.
• Adjusted how "eliminated by" is assigned. Previously player A would have to cause damage to player B for it to count that A eliminated B. For example, if a Grenade exploded far enough not to cause damage but pushed the player off the map, game seen it as if f they eliminated themselves. This was now fixed.
• Added a "Disconnected" status icon. status icon has been added - a red lightning on a black background, which indicates that the player has disconnected and left the game.

BUG FIXES:

• Sometimes first person view / third person view cameras would not align properly when choosing / doing actions. This has been fixed.
• Fixed the bug where the cursor would sometimes disappear during the game.

CHANGELOG:

• Pick ups can now carry more than one item! To make the game more dynamic - a bit less about jumping and a bit more about mayhem, pick ups can now carry from 1 to 4 items!
• 5 new maps added! 3 Tiny Forest maps and 2 Tiny Canyon maps were added to the roster!
• "Small" maps were renaned to "Medium" maps. The three size categories for maps will be "Tiny", "Medium" and "Big."
• Some touch up were made to Race Maps. With the intention to make the races a bit easier and more enjoyable.
• Objects turn a bit more transparent, when obscuring the view. This change was made to allow better visibility. They also turn transparent faster.

BUG FIXES:

• Fixed the bug where pick ups would occasionally spawn too close, making the player get the weapon right away.
