Getting past wave 30 in ST: Blockade Battlefront is a milestone. Reaching wave 50 consistently separates casual players from dedicated ones. Pushing past wave 70 requires mastery of every system in the game.
This guide breaks down the late-game wave structure, boss mechanics, positioning strategies, and team coordination protocols that carry you from wave 40 through wave 90 and beyond.
Wave Structure Overview
Blockade Battlefront’s Classic (Endless) mode runs 90 waves before looping. Understanding the wave pattern is the foundation of late-game survival.
Wave Categories
| Wave Range | Category | Enemy Density | Threat Level | Key Concern |
|---|---|---|---|---|
| 1-10 | Early | Low | Very Low | Learning phase |
| 11-24 | Early-Mid | Medium | Low-Medium | Build econ |
| 25-40 | Mid | Medium-High | Medium | Farm Cen, build loadout |
| 41-50 | Mid-Late | High | High | Enemy scaling accelerates |
| 51-60 | Late | Very High | Very High | Crowd control mandatory |
| 61-70 | Late-Endgame | Extreme | Extreme | Coordinated team required |
| 71-80 | Endgame | Extreme+ | Extreme+ | 100M skins strongly recommended |
| 81-90 | Hell | Maximum | Maximum | Wave 90 = all bosses at once |
The 5-Wave Helicopter Cycle
Every 5 waves, a helicopter arrives. It provides:
- 30-second shop window: Buy weapons, Titans, ammo, and character unlocks
- Full team respawn: Dead teammates respawn for free
- HP restoration: All surviving players are healed
The cycle:
- Waves X1-X4: Standard or swarm waves (based on wave number)
- Wave X5/X0: Boss wave (every 5th wave)
The helicopter is your lifeline. Miss it, and you fight the next 5 waves without resupply.
Boss Wave Mechanics (Every 5th Wave)
Boss waves are the primary run-enders in late game. Each boss wave has a major boss plus adds. Bosses gain significant HP and damage scaling as wave numbers increase.
Boss Wave Protocol
| Phase | Action | Timing |
|---|---|---|
| Prep | Reload all weapons, check ammo, deploy fresh Titan | Before wave starts |
| Spawn | All players identify boss location and type | First 3 seconds |
| Focus | Entire team focus-fires boss. Do NOT split damage. | Until boss reaches 50% HP |
| Clear | Boss enrages or spawns additional adds at 50% | AoE player clears adds, others continue boss DPS |
| Finish | Burn boss from 50% to 0%. Use Utam Titan if available. | Final push |
| Reset | Reload, repair Titans, reposition for next wave | Before next wave spawns |
Boss Types
| Boss | Wave Pattern | Threat | Counter |
|---|---|---|---|
| G-Toilet | Early bosses (waves 5, 10, 15…) | Moderate damage, large HP pool | Standard focus-fire, kite in circles |
| Large Toilet | Mid bosses (waves 25, 35, 45…) | High damage charge attack | Spread out to avoid charge, Bazooka AoE for adds |
| Dr. Toilet | Wave 90 (final boss) | Extreme damage, summons other bosses | Uptati or 3 Special Titans required, full team coordination |
Wave-by-Wave Strategy: 40-70
Waves 41-45: The First Difficulty Spike
At wave 41, enemy HP and damage both jump noticeably. This is where undergeared players start dying.
| Wave | Type | Strategy |
|---|---|---|
| 41 | Standard | Test your DPS — if enemies take more than 5 seconds to kill, your weapon is underleveled |
| 42 | Swarm | Bazooka AoE mandatory. Group enemies, fire into clusters |
| 43 | Standard | Hold standard positions, conserve ammo |
| 44 | Swarm | Second swarm wave — if ammo is low, melee weaker enemies |
| 45 | Boss | First serious boss threat. Deploy Titan Cameraman, focus-fire |
Checkpoint: If you die during waves 41-45, your loadout isn’t ready for late game. Farm more Cen in the 25-40 range before attempting again.
Waves 46-50: Position Discipline
Enemy speed increases. Positioning mistakes that were survivable in mid-game now kill you in 2-3 hits.
- Never stand in the open — always have a wall or obstacle nearby
- Never peek the same angle twice — reposition after every engagement
- Always know where your nearest cover is
- Always track your teammates’ positions — if they go down, adjust your hold
Waves 51-55: Swarm Hell
Waves 51-54 feature the densest enemy clusters in the game. Bazooka becomes your primary weapon.
| Technique | Description |
|---|---|
| Funnel | Position so enemies approach through a narrow corridor — one Bazooka shot hits everything |
| Kite | Walk backwards while firing. Enemies clump up chasing you, creating perfect AoE targets |
| Rotate | If a lane is overrun, call it out and rotate to a secondary position. Don’t die holding a lost lane |
Waves 56-60: Boss Gauntlet
The wave 55 and 60 bosses have significantly more HP than earlier bosses. Utam Titan shines here.
- Wave 55 boss: Deploy Utam at the start. Its single-target damage is unmatched.
- Wave 60 boss: This is a team DPS check. If you can’t kill it before the helicopter timer runs out, your combined damage is too low.
Waves 61-70: Endurance Test
These waves test everything: ammo management, Titan rotation, team coordination, and individual mechanics.
Titan Rotation Pattern:
- Deploy Titan Cameraman at wave 61 start
- Rotate to Jetpack Double Plunger at wave 64
- Return to Titan Cameraman (repaired/recharged) at wave 66
- Deploy Utam for the wave 65 and 70 bosses
- Use helicopter at wave 65 and 70 to repair all Titans
Ammo Conservation Tips:
- Don’t shoot enemies your Titan can handle alone
- Use melee on isolated weak enemies to save ammo
- Buy ammo at EVERY helicopter — even if you’re at 70%, top off
- Running out of ammo mid-wave past wave 60 is almost always fatal
Wave 90: The Hell Wave
Wave 90 is the ultimate challenge in Classic mode. Dr. Toilet spawns alongside every other boss from previous waves.
Requirements to Clear Wave 90
| Requirement | Minimum | Recommended |
|---|---|---|
| Team size | 3 players | 4 players (full) |
| Character | Large Cam (Villain Arc) or better | Uptake Titan (100M) or Tackleman (100M) |
| Titans | 3 Titans | 3 Special Titans or Uptati |
| Weapons | Minigun + Bazooka | Minigun + Bazooka (both fully upgraded) |
| Communication | Text chat | Voice comms (Discord) |
Wave 90 Strategy
- Pre-wave prep: All 4 players deploy their strongest Titan simultaneously
- Boss priority: Dr. Toilet > G-Toilet > Large Toilet > adds
- Tank assignment: Player with highest HP/sustain holds Dr. Toilet aggro
- AoE player: One player dedicated to clearing adds so the team isn’t overwhelmed
- Titan sacrifice: If a Titan is about to die, use it to body-block a boss charge — better the Titan dies than a player
- No respawns: Dead players cannot respawn until the next helicopter. Staying alive matters more than dealing damage.
Reward: Burning Flame
Clearing wave 90 for the first time rewards the Burning Flame item — a cosmetic that shows other players you’ve conquered the hardest PvE content in the game.
Positioning and Map Control
Standard Hold Positions
Every map has 2-4 defensible positions. The best positions share these traits:
- Chokepoint: Enemies approach through a narrow path
- Cover: Hard cover (walls, crates) to break line of sight
- Escape route: At least one path to retreat if overrun
- Sightlines: Clear view of approaching enemies for early targeting
When to Abandon a Position
- 3+ enemies have entered melee range
- Your Titan dies and the replacement isn’t ready
- A teammate in your lane goes down
- You’re below 30% HP with no healing available
Call out “rotating” in chat so teammates know a lane is being abandoned and can adjust.
Post-Wave 90: The Loop
After clearing wave 90, the game loops to wave 1 with scaled difficulty. All your Cen, weapons, Titans, and characters carry over.
Loop 2 changes:
- Enemy HP: +50%
- Enemy damage: +40%
- Enemy spawn rate: +25%
- Cen rewards: +100%
Experienced teams can clear 2-3 full loops before the scaling becomes overwhelming. Loop 2 wave 90 is considered the true endgame challenge — only a handful of fully coordinated teams with full 100M skin rosters have cleared it.
Late-game Blockade Battlefront rewards preparation, coordination, and composure under pressure. Know the wave patterns, rotate your Titans on schedule, never miss a helicopter, and trust your team.
