Chara Upgrades

In Chara Upgrades, you try to go as far as possible inside dungeons to complete missions for the guild. Increase your reputation to unlock new fighters to fight for you inside the dungeons. Use their powers and your items cleverly to get the most out of them. All the fighters start with the same stats, but you'll find cards that make them more potent in the dungeons.

Modes:

Story Mode: This mode introduces players to the game's rich universe through a structured narrative path. As you guide your guild through various dungeon stages, you'll encounter key characters, piece together lore, and face unique boss battles. Each chapter reveals more about the world’s history and your guild’s role in it. It’s an ideal entry point for newcomers looking to ease into the game's mechanics while enjoying a story-rich adventure.

Challenge Mode: For those seeking higher stakes, Challenge Mode offers condition-specific missions and limited-time events. These dungeons often come with special modifiers—such as tougher enemies, resource constraints, or map restrictions—that push players to rethink their tactics. Successful completion brings valuable rewards, rare cards, and an extra sense of achievement for those who master its conditions.

Multiplayer Co-op: Chara Upgrades also supports online co-op, allowing friends or random players to team up in real-time. Coordination becomes key, as players combine card strategies and class roles to overcome more difficult dungeon layouts. This mode adds a social layer to the game and is perfect for players who enjoy teamwork and shared victories.

Dynamic Card System: At the heart of Chara Upgrades APK is its dynamic card system. Every card you find or earn can shift your playstyle dramatically—from defense boosts to attack modifiers or utility skills. This system encourages experimentation, letting players craft different builds each run and making every dungeon attempt feel fresh and unique.

Features:

Straight to the Action: There’s no fluff. You dive straight into the core gameplay without excessive storytelling or hand-holding.

Strategic Layering: Every run feels fresh thanks to dynamic dungeons and randomized challenges. Your choices in character upgrades and squad formation truly matter.

Addictive Replay Loop: The “one more run” appeal is strong. With each mission, you’re tempted to push your luck further — testing your skills and adapting strategies.

Card-Based Mechanics: The clever use of cards for skills and upgrades adds a layer of unpredictability and excitement, making each playthrough unique.

Improves Decision-Making: With its risk-reward structure, players constantly make real-time choices that impact survival and success.

Promotes Tactical Thinking: The game challenges you to think several moves ahead, encouraging mental agility.

Highlights:

Permanent power boosts: In some cases, players will often have to find ways to collect a large amount of experience points. Relation points also play an important role in this game, so they will be able to boost the character’s ability to fight against enemies many times.

Enhance combat potency: By completing missions well, your reputation can increase in the most positive way. This is absolutely necessary because it is a prerequisite for quickly unlocking completely new characters. From there, finding powerful cards also becomes easier in dungeons.

Explore diverse dungeons: If a dungeon becomes challenging, each player will often find a way to complete them or replay them many times. Failure is not a factor that makes you feel disappointed but will be the motivation to innovate impressive strategies and help unlock areas related to the Infinigeon.

Unlock unique rewards: Different characters will continuously be unlocked in order based on the player’s performance. At the same time, adding monsters is often a necessary support mechanism because everyone often wants to have companions and boost stats for the main character.

Strengths:

Procedural Challenges: Brave three unique dungeons filled with shifting traps, enemies, and loot, culminating in the Infinigeon—an endless mode where only the strongest survive.  

Mission-Driven Progression: Complete guild objectives to unlock rare cards, XP boosts, and hidden paths, ensuring every run feels fresh and rewarding.  

Monster Taming: Capture defeated foes to earn exclusive rewards from the enigmatic Monster Tamer, adding tactical depth to your team.  

Customizable Fighters: Recruit allies with identical base stats, then personalize their abilities using dungeon-earned cards for unique synergies.  

Permanent Upgrades: Spend hard-won XP and relation points on global buffs or intimate “training” sessions to strengthen fighters across runs.  

Resource Management: Balance consumables, card draws, and risk-reward decisions to optimize survival in high-stakes encounters.  

Changelog:

Here is what the v1.04 hotfix changes:

At the title screen, the button “music” is replaced by the button “Options”

Chika’s scene “Uncommon 2” has a new picture

During dialogues, the “hide” button has a little space to its right so it’s not stuck to the border of the screen

A new option to remove moaning sounds

No fade to black when switching characters at home and school

Yogurt voices were altered to make them work better in the browser version

The following issues won’t be fixed:

When playing the web version on Firefox, a blue overlay appears. It’s a Firefox bug that affects all Unity games (so all my games). I hope it will be fixed quickly.

When going very, very far in a dungeon, the monsters’ HP turns negative. At this point, you have clearly finished the game. Let’s say it’s like in Tetris; breaking the game is the true ending.

Thanks to those who reported issues. If you encounter any problems, please let me know.

Final Verdict:

Okay, here's the lowdown. Chara Upgrades is a mobile dungeon-crawler RPG that doesn’t waste time with fluff. It throws you straight into gritty, ever-changing dungeon runs where your crew of fighters starts off on the same level and what you do from there? That’s all on you. It’s tactical, a little ruthless, and pretty addictive if you're into card-based strategy, squad-building, and pushing your luck deeper with each mission. No gimmicks, just smart gameplay moves and a constant loop of “okay, one more run.”
