Introduction to The Battle Bricks Chapter 4: Across Heaven

You've conquered Area 51, but the real test has just begun. The Battle Bricks Chapter 4, also known as "Across Heaven," marks a significant turning point in the game. This is where the difficulty curve steepens, new enemy types are introduced, and the game's mechanics are pushed to their limits. If you've been coasting through the earlier chapters, Chapter 4 will demand a more strategic approach, better unit management, and a willingness to grind for upgrades.

This chapter is a community-proven challenge, often described as the halfway point of The Battle Bricks. It's not just about brute force anymore; you need to understand enemy traits, utilize specific units, and adapt to ever-changing battlefield conditions. Based on extensive player experience and official wiki data, this guide will walk you through everything you need to know to conquer Across Heaven.

New Enemy Types and Mechanics in Chapter 4

The most significant change in the battle bricks chapter 4 is the introduction of the Angel trait. These enemies are not just tougher; they have unique abilities that can completely disrupt your standard strategies.

The Angel Trait Explained

Angels are the new standard enemy type you'll face. According to the game's wiki, they have average health but possess a crucial ability: they immediately revive to half their health after taking a fatal hit. This means you can't rely on one-shot kills or quick bursts of damage. You need sustained firepower to put them down for good. Many Angel enemies also have Armor, making them even more resilient.

Flying and Background Enemies

Chapter 4 introduces the first non-summon enemies that can fly by default, such as Flight and Airhead. These units often stay in the background, making them untouchable by your melee battlers. This forces you to adapt your lineup. You will need to rely heavily on ranged units to deal with these aerial threats. As one player noted, "We got to have more ranged units out" to counter the "angels stalking the skies, throwing grenades."

New Hazards and Cannons

The environments in Chapter 4 are more than just set dressing. You'll encounter:

Fog: This hazard decreases the range of your units and makes it harder to see the battlefield. It's a direct counter to long-range strategies.
Lightning: Surprisingly, this hazard is a buff that speeds up all units on the field. It can be a double-edged sword, speeding up your attackers as well as the enemy's.
Liberty Cannon: A new cannon that grants your team temporary invincibility. However, many players find it underwhelming, comparing it to a rarely-used super ability in Cuphead. Its short duration makes it less valuable than other cannons.

Key Battlers and Strategies for Success

Your success in the battle bricks chapter 4 hinges on having the right units and using them effectively. Based on player reports and gameplay footage, here are the standout units for this chapter.

Essential Units to Upgrade

Unit	Role	Why It's Crucial in Chapter 4
Time Battler	Tank / Disabler	High health and immunity to stun make it invaluable against the final boss's AoE attacks.
Doombringer / Deathbringer	Tank	Expensive but serves as a decent tank. Its alt form, Deathbringer, has lower defense but can be situationally useful.
Titan Battler	Tank / Damage	Replacing your standard battler with Titan is a great idea. It has a boatload of health and can withstand heavy punishment.
Ranged Units	Damage	Essential for dealing with flying and background enemies. Units like Slinger Battler and Paintball Battler are key.
Tiny Battler	Utility	As discovered by one player, this unit can be the "savior" against the final boss's grab attack, as it is not targeted.

Unit Comparison: Doombringer vs. Titan Battler

Feature	Doombringer	Titan Battler
Cost	High	Moderate
Health	High	Very High
Damage	Moderate	High
Stun Immunity	No	No
Best Use Case	Secondary tank, cost-effective damage soaker	Primary frontline tank, holding the line

Boss Battles in Across Heaven

The battle bricks chapter 4 is notorious for its large number of bosses. The wiki lists a total of 12 bosses, including their alt forms. This is more than any other chapter in the game. Here are the most memorable ones based on player experience.

Chessmaster (The Queen)

The first major boss is a giant chess piece, the Queen. She is a handful because she can fly past your defenses, use intangibility, and send out mini versions of herself. This fight requires you to have a strong backline and the ability to quickly deal with the mini-queens. Many players found success by spamming units and relying on the "Powerhouse" strategy, even if it's not always optimal.

Judgement (The Lightning Judge)

This boss appears in a courtroom setting and is known for spawning in the middle of the battlefield, not from the enemy base. He constantly says "Prepare thyself" and can summon lightning that one-shots your units. The key to this fight is to have a high-damage unit like Time Battler that can survive his initial attacks and deal consistent damage.

Sisyphus / Cesus (The Final Boss)

The final boss of Chapter 4 is a celestial tea pot man, often called Sisyphus or Cesus. This fight is a marathon, not a sprint. The boss has several phases and a variety of devastating attacks:

AoE Attacks: He loves using area-of-effect attacks, making a stacked frontline ineffective.
Pushback and Stun: His attacks can push your units back and stun them.
Unit Grabbing: In later phases, he will periodically grab your strongest units and instantly kill them by sending them to "heaven." This is where Tiny Battler becomes invaluable, as it is not targeted by this attack.
Teapot Flankers: He spawns teapot enemies that can flank your base.

The winning strategy, as confirmed by players, involves using a max-level Time Battler (immune to stun) and a max-level base to spam units. The goal is to overwhelm the boss while your Time Battler tanks the damage.

Progression and Grinding Tips

Chapter 4 is a significant jump in difficulty, and you will likely need to grind. Here are some tips from player experience to make the process smoother.

Effective Grinding Strategies

Finish Old Sub-Chapters: Go back and complete earlier sub-chapters you might have skipped. The "Red Herring" sub-chapter, for example, provides a good amount of XP and is much easier now that your units are stronger.
Focus on Key Upgrades: Prioritize upgrading your main tank (Time Battler or Titan) and your most powerful damage dealer. Don't spread your XP too thin.
Max Your Base: Your base health is crucial in the later stages of Chapter 4. Invest in upgrading it to survive the final boss's long-range attacks.
Use the Right Cannons: The "Liberty" cannon is often considered weak. Stick with the standard cannon or one that provides consistent damage or crowd control.

Recommended Unit Progression

Stage of Chapter	Recommended Units to Focus On
Early (Sections 1-2)	Ranged units (Slinger, Paintball), Barbaric Battler, Doombringer
Mid (Sections 3-4)	Time Battler, Titan Battler, upgraded Kamikaze Battler
Late (Sections 5-6)	Max-level Time Battler, Max-level Base, Tiny Battler
