The Battle Bricks Chapter 4: Across Heaven isn't just another set of levels; it's a brutal gauntlet that tests everything you learned in the previous chapters. If you are deep into the battle bricks chapter 4, you have likely run face-first into High Angels, devastating Teapots, and a final boss that literally throws your best units into the sun. In this guide, we will break down exactly how to conquer the battle bricks chapter 4, from unit selection to boss phase strategies.
Set in the medieval cloud realm, this chapter forces a massive playstyle shift. Melee-heavy lineups simply do not cut it anymore. You will need a deep roster of ranged units, specialized tanks, and a lot of patience. Based on firsthand player experience and community breakdowns of the update, here is your ultimate roadmap to victory.
New Threats in the Sky: Enemies and Hazards
The moment you enter the first stage, the game throws new mechanics at you. The "Across Heaven" sub-chapter immediately introduces flying Angels. These units hang in the background and require specific ranged units to hit. Players report that this is a sign of things to come, as the game introduces enemies that are literally unreachable by standard melee fighters.
The Angel Menace
Angels come in two primary types. The standard Angel hovers in the background, but a "High Angel" variant flies far higher. Player experience explains that you "need even farther range units to deal with those guys." If you do not have a Sniper Battler or similar long-range unit, these enemies will stack endlessly and destroy your defenses.
The Teapot Tyranny
The most devastating common enemy in the battle bricks chapter 4 is the Teapot. These steampunk enemies shoot three missiles after a short delay. While their damage is manageable, the "Teapot Flanker" variant is universally hated by the community. This enemy makes your front-line units sit down, leaving them completely vulnerable to damage. The best counter is a heavy backline of ranged units to kill them before they reach your meatshields.
| Enemy Name | Type | Threat Level | Recommended Counter |
|---|---|---|---|
| Angel | Ranged (Background) | Medium | Standard ranged units (e.g., Sniper Battler) |
| High Angel | Ranged (Very High Background) | High | Long-range specialist units |
| Viking | Melee | Medium | Rush down or isolate |
| Samurai | Melee (Warp) | Medium | Area denial, stall with meatshields |
| Singer | Support (Buff) | High | Prioritize killing her |
| Teapot Flanker | Debuffer (Sit Down) | Critical | Kill with ranged before they reach front line |
Environmental Hazards
Hazards are back and more annoying than ever. The "Fog" hazard reduces your unit's range, making it very hard to snipe threats quickly. Conversely, the "Lightning" hazard is actually a buff that speeds up all units. Finally, many stages feature enemies in the background layer that you cannot touch without proper range.
Best Units and Loadout for The Battle Bricks Chapter 4
If you try to brute force this chapter with your standard loadout from Chapter 3, you will fail. The community experience heavily emphasizes specific counters for the final boss, Sisyphus.
The MVP: Time Battler
If you have been sleeping on Time Battler, now is the time to upgrade him. He is the most powerful unit for this chapter. According to community reports, "the reason why Time Battler is so good on this stage is because, one, he has a boat load of health, but two, he doesn't get stunned." The final boss and Teapot stages rely heavily on stun and pushback, making Time Battler a literal wall.
The Secret Weapon: Tiny Battler
The hero of the final boss fight is surprisingly Tiny Battler. Sisyphus has a devastating "grab" mechanic where he picks up your strongest unit and instantly kills them. Spamming Tiny Battler (who is too weak to be a worthwhile grab target) allows your damage dealers to survive.
| Unit Name | Tier | Role in The Battle Bricks Chapter 4 |
|---|---|---|
| Time Battler | S | Immunity to stun is mandatory for Sisyphus |
| Tiny Battler | S | Best meat shield to avoid boss grab mechanic |
| Sniper Battler | A | Required for background Angels and High Angels |
| Titan Battler | A | High HP and damage for general pushing |
| Doombringer | B | Decent tank but very expensive to deploy |
| Kamikaze Battler | B | Great for clearing crowded Teapot stacks |
Boss Battle Strategies: Phase by Phase
The Battle Bricks Chapter 4 features three major boss fights. The first is the Queen, a chess piece that can fly, turn intangible, and spawn clones. The second is a "Lightning Judge" that summons lightning and spawns endlessly. The real challenge, however, is the final boss: Tea Time (Sisyphus).
Based on the journey of a dedicated player and community reports, the Sisyphus fight breaks down into distinct phases that require specific reactions.
| Phase | Attack Pattern | Player Action | Key Strategy |
|---|---|---|---|
| Phase 1 | Basic melee, slow attacks | Build economy, deploy tanks | Doombringer or Titan work well here |
| Phase 2 | Teapot storms, AoE pushback | Keep range, watch for stun | Time Battler is essential to tank this phase |
| Phase 3 | Long range base bombardment | Spam units, use Liberty cannon | Keep your base health high |
| Phase 4 | Grab Mechanic (removes strongest) | Spam cheap units | Tiny Battler is the savior here |
Defeating Sisyphus
The first attempt often ends in disaster. The boss "really loves his AoE attacks" and the "amount of pushback and stun attacks are actually unbearable." Players report that Sisyphus "just sends out a bunch of teapots and then somehow explode." If you did not upgrade your base health, his phase 3 air attack will hit your base directly from across the map.
The winning strategy requires grinding. You must max out your base health and upgrade Time Battler. Once you enter phase four, spam Tiny Battler. The boss will grab him, laugh, and toss him away, leaving your real damage dealers alive to finish the job.
Progression Guide: What to Upgrade First
Grinding is not a shame in this chapter. If you hit a wall at Sisyphus, community experience suggests going back to finish early sub-chapters (like "Red Herring") to farm the massive amount of XP needed.
| Priority | Upgrade Target | Reason |
|---|---|---|
| 1st | Time Battler | Essential tank for the final boss |
| 2nd | Base Health | Survives the phase 3 long-range bombardments |
| 3rd | Ranged Units | Mandatory for clearing background Angels/Teapots |
| 4th | Doombringer | Decent general tank for mid-game stages |
| 5th | Bomb Battler | Great for clearing swarms of teapots |
Common Mistakes and How to Avoid Them
Ignoring the Teapots: These are the most dangerous common enemy. If you let them stack, they will delete your frontline. The solution is simple: bring ranged units. Do not leave the base without them.
Using Only Strong Units Against Sisyphus: The grab mechanic specifically targets your strongest unit. A single hyper-leveled unit is a trap. You need a balanced army backed by an endless stream of cheap units like Tiny Battler.
Relying on the Liberty Cannon: The new invincibility cannon sounds amazing, but it is incredibly difficult to time perfectly against the chaotic attacks of the final boss. Player experience confirms it often feels useless unless you have perfect timing. Focus on unit composition and base levels instead.
Not Grinding Enough:The battle bricks chapter 4 has a steep difficulty spike. Players who failed multiple times found success only after leaving to grind XP. If you can't beat a stage after five tries, farm XP on previous chapters to boost your units.
FAQ: The Battle Bricks Chapter 4
Q1: What is the hardest boss in The Battle Bricks Chapter 4? A: By far, the final boss, Sisyphus (also known as Tea Time). His multi-phase fight, devastating AoE stuns, and unique grab mechanic that kills your strongest unit instantly make him the wall that most players hit.
Q2: What are the best units for The Battle Bricks Chapter 4? A: Time Battler is the MVP due to his stun immunity and massive health pool. You also need strong ranged units to deal with background Angels and Teapots. Tiny Battler is a hidden gem for the final boss, acting as fodder for the grab attack.
Q3: How do I kill the background enemies in The Battle Bricks Chapter 4? A: You cannot melee them. You must equip units that have a specific "ranged" or "sniper" tag. Units like Sniper Battler, or any character whose attack animation travels a very long distance, are required to clear these threats.
Q4: Why is my base dying so fast in the final stage? A: This is from Sisyphus's long-range attack in phase three. The solution is to upgrade your base health using XP. You also need tanky units on the field to push the boss back and absorb some of the damage.
