How Cen Works in BBF
Cen is the in-game currency in ST: Blockade Battlefront. Every enemy kill drops Cen, and every Titan purchase costs Cen. The economy is tight — you can’t buy everything, so every spending decision matters.
Cen Drop Rates by Wave Tier
| Wave Range | Cen per Kill | Enemies per Wave | Max Cen per Wave |
|---|---|---|---|
| 1-10 | 1-2 | 15-25 | 25-50 |
| 11-20 | 2-3 | 25-40 | 50-120 |
| 21-30 | 3-4 | 40-60 | 120-240 |
| 31-40 | 4-5 | 50-75 | 200-375 |
| 41-50 | 4-6 | 60-90 | 240-540 |
| 51-60 | 5-7 | 70-100 | 350-700 |
| 61-70 | 6-8 | 80-120 | 480-960 |
| 71-80 | 7-10 | 90-140 | 630-1,400 |
| 81-90 | 10-15 | 100-160 | 1,000-2,400 |
7 Cen Farming Methods That Actually Work
Method 1: Early Efficiency (Wave 1-20) — ~1,200 Cen Banked
This is the foundation. Mess this up and you’re behind for the entire run.
The key is minimal spending. You only need two purchases: Titan Cameraman (350 Cen) and Titan Speakerman (900 Cen). That’s 1,250 Cen total. Every other base unit is a trap — they fall off by wave 15 and you never get that Cen back.
| Wave | Action | Cen After |
|---|---|---|
| 5 | Buy Titan Cameraman (350) | ~50 |
| 10 | Buy Titan Speakerman (900) | ~100 |
| 15 | Save | ~450 |
| 20 | Save for upgrade | ~1,200 |
Method 2: Wave 25-35 Sweet Spot — ~3,000 Cen per 10 Waves
This is the most efficient farming window in the entire game. Enemy density is high enough to produce good Cen income, but enemy HP hasn’t spiked yet so your Upgraded Cameraman can still one-shot most units.
Requirements: Upgraded Titan Cameraman + any secondary Titan
Strategy: Don’t push waves quickly. Let enemies accumulate at chokepoints before clearing them. More enemies on screen = more Cen drops per Titan attack. Rushing waves actually reduces your income.
Method 3: Dual Upgraded Carry (Wave 35-45) — ~4,500 Cen per 10 Waves
Once you have both Upgraded Cameraman and Upgraded Speakerman, your clear speed hits a sweet spot: fast enough to clear waves without leaking enemies, but not so fast that you miss Cen drops.
Position Upgraded Speakerman on the lane with the most enemies and Upgraded Cameraman on the boss lane. The Speakerman’s rapid fire generates a steady stream of Cen while Cameraman focuses down high-value boss kills worth 20-30 Cen each at this stage.
Method 4: TV Man AoE Cen Vacuum (Wave 46-60) — ~6,000 Cen per 10 Waves
Once Titan TV Man is deployed, its AoE attack tags every enemy on screen. Tagged enemies that die to any source still drop full Cen. Position TV Man in the center, let its AoE tag everything, and let your other Titans finish them off.
This is the method that funds your Upgraded TV Man purchase. A single well-executed wave 50-55 cycle can net you 700-900 Cen.
Method 5: Cineman Boss Farming (Wave 55-70)
Titan Cineman’s 15% damage vulnerability debuff makes bosses die faster. Faster boss kills = faster wave clears = more waves per minute = more Cen per minute. It’s a compounding advantage.
Against the wave 60 boss (200+ HP with shield), Cineman effectively reduces its HP from 200 to 170 for your entire Titan lineup. That 30 HP difference saves 5-8 seconds per boss wave.
Method 6: Shield Wave Optimization (Wave 65-75)
Shielded enemies are a Cen trap. They take forever to kill without armor-piercing units, which means slower waves and lower Cen per minute. If you don’t have Titan Drill Man by wave 65, you’re bleeding potential income.
The math: A shielded enemy takes 5x longer to kill without armor piercing. Over 3 shield waves (65, 69, 73), that’s roughly 1,800 Cen in lost income from slower clear speed. Titan Drill Man costs 5,000 Cen but pays back ~1,800 of that in saved time — and you need it for the final push anyway.
Method 7: Late-Game Max Clear (Wave 76-90)
By this point, Cen isn’t about saving — it’s about spending everything efficiently to survive. Every Cen you’re holding when you die is wasted. Max out Titan levels, buy the final upgrades, and push.
Common Cen Spending Mistakes
| Mistake | Cen Wasted | Why It’s Bad |
|---|---|---|
| Buying 3+ base units before wave 10 | ~500 | Base units can’t be upgraded into their better versions — they become dead weight |
| Buying Large Cameraman | 650 | Looks tanky, but Upgraded Cameraman does the same job better for a bit more |
| Skipping Titan Cineman | 4,200 saved, but slower boss clears | The 15% vulnerability debuff saves more time (and earns more Cen) than its cost |
| Upgrading Titans in the wrong order | Varies | Always upgrade Cameraman first, Speakerman second, TV Man third |
| Holding Cen past wave 80 | Potentially 2,000+ | Unspent Cen at death is the biggest waste in the game |
Cen Income Milestones: Are You On Track?
| Wave | Minimum Cen Earned (Good Run) | Key Purchase Checkpoint |
|---|---|---|
| 10 | 900+ | Titan Speakerman purchased? |
| 20 | 2,500+ | Upgraded Cameraman purchased? |
| 30 | 6,000+ | Upgraded Speakerman purchased? |
| 40 | 10,500+ | Titan TV Man purchased? |
| 50 | 16,000+ | Titan Cineman purchased? |
| 60 | 22,000+ | Upgraded TV Man purchased? |
| 70 | 28,000+ | Titan Drill Man if needed? |
| 80 | 34,000+ | Everything invested? |
If you’re below these numbers by wave 40, you’re overspending on base units or clearing waves too fast and missing Cen drops. Slow down and let enemies accumulate.
