Game Mechanics

Player Controls and Actions

In OpenATBP, controlling your champion is simple but full of depth. Here's how to command the battlefield:

Champion Abilities

Each champion has a unique set of three active abilities, mapped to the Q, W, and E keys:

No Mana in OpenATBP:

OpenATBP does not use a mana system. You can cast abilities as long as they're off cooldown, giving you more freedom to focus on timing and positioning rather than resource management.

Passive Powers

Every champion also has a passive ability:

Mastering your champion's abilities and knowing when to strike (or retreat!) is key to winning matches.

Damage and Death

In OpenATBP, every unit (except Magic Man's decoy) has Health Points (HP) that decrease as they take damage. Once a unit's HP hits zero, it's knocked out (KO'd).

Champion Knockouts & Respawning

When a champion is KO'd, they will respawn at their team's base after a short delay.

Your champion's respawn time increases as the match progresses:

For example:

This mechanic helps speed up early-game action while adding tension to late-game fights.

Gaining Experience & Leveling Up

Defeating enemy champions, minions, and jungle creeps earns your champion Experience Points (XP).

Earning enough XP will cause your champion to level up.

Leveling Benefits

Every level increases your base stats, like health or damage.

You also gain a Skill Point, which you can invest into Battle Junk — your champion's backpack of upgrades.

Battle Junk Upgrades

Each champion has a unique backpack that offers passive stat boosts. Investing skill points into these items improves:

Choosing how to upgrade your Battle Junk is key to tailoring your champion's strength in each match.

Combat System

In OpenATBP, all units deal damage, but not all damage is the same. Understanding how damage works is key to mastering battles.

Damage Types

There are two main types of damage in the game:

Each champion may scale differently with these damage types, so knowing whether a skill deals AD or PD can influence how you build or counter them.

Disconnect Buffs (DC Buffs)

To help balance uneven matches caused by disconnects, OpenATBP provides stat boosts to players left behind when their teammates go offline.

These buffs are only active in real matches (not PvP test matches), and are automatically applied when teammates disconnect. If both teams have disconnected players, the buffs cancel each other out.

How It Works

If one teammate disconnects, all remaining players (and their minions) receive:

If two teammates disconnect, you gain an additional buff:

If all three team members disconnect, that team will automatically forfeit the match.

These buffs are meant to give solo or outnumbered players a fighting chance - but winning a 1v3 still takes serious skill (and maybe a little luck).

Crowd Control Effects (CC)

Crowd Control, often shortened to CC, refers to abilities that restrict a champion’s movement, actions, or both. OpenATBP features a variety of CC effects, each with different mechanics and counterplay.

Below is a breakdown of each type of crowd control effect you might encounter:

Root

Stun

Charm

Slow

Fear

Silence

Blind

Polymorph

Airborne

Pro tip: Some champions have passives or abilities that help reduce or cleanse crowd control effects — keep an eye out for them!

Altars

Altars are powerful control points that appear throughout the battlefield in OpenATBP. Securing them provides your team with strong temporary buffs and can swing the outcome of a match.

Mid Altar (Offensive Buff)

Side Altars (Defensive Buffs)

Altar Capture Speed

The time it takes to capture an altar depends on how many more teammates are standing on it compared to enemies:

Re-Capture

If an altar is captured, it will be available for capture again after 3 minutes.

Goo Buff Synergy

Players with the Goo Buff (earned from the Goo Monster) will amplify altar effects by 50%, giving:

Also, if a player has 0 Armor or Shields, Side Altar buffs grant a minimum of +5 to each, ensuring everyone benefits from the defense boost.

Health Packs

Health Packs are valuable pickups scattered throughout the battlefield in OpenATBP. These can be a lifesaver during intense moments, providing both instant healing and a temporary health regeneration boost.

How Health Packs Work

Health Pack Timing

Strategic Use

  • Health Packs are limited, so always be aware of their locations and respawn times.
  • They're crucial for sustaining health in longer fights or when pushing objectives.
  • Spawn Times and Respawn Times

    Understanding spawn times and respawn intervals is crucial to mastering the flow of the match in OpenATBP. Below is a breakdown of the different units and their respective timings.
