Strategy
This section was last updated for: version 51.1
Long Life Spikes covers Spike Factory's typical weakness at the start of rounds by carrying over its stockpile from the previous round. It works best when it spends most of its time building up spikes, not being pressured by Bloons, and is generally not worth it on Apopalypse and other modes that preserve spikes between rounds by default. Spike piles are not saved when retrying last round in CHIMPS, using a Continue, nor when loading a saved game, making them weaker outside of a Black Border context.
The tower prefers the 1-0-3 crosspath for lower cost, slightly higher damage in most contexts, and reducing the number of Acidic Mixture Dips needed for full uptime if Alchemists can't be isolated properly. Berserker Brew is a very important buff for the tower, cheaper than Long Life Spikes while quadrupling its damage output with both buffs active, making the tower stronger than Deadly Spikes for less cost. Stronger Stimulant, however, is still too expensive for what it offers at this tier.
Long Life Spikes is typically used as a stepping stone for Perma-Spike, but in the meantime it effectively blocks fast and aggressive early game rounds such as 36 and 40, as well as camos up through 50, as long as the pile is kept safe the round before or stalling is used. Manual targeting can also let the tower dump spike piles onto blimp layers in mid-game, but without heavy stalling it falls short in this role compared to MOAB SHREDR.
Late game, manual targeting combined with stalling and damage debuffs can be used to snipe DDT layers and the round 100 BAD layer to serve as a mini-Perma-Spike. With Embrittlement and 2-4-0 Glue Strike active as Bloons enter the pile, a fully stalled spike pile deals 7k-9k damage per Long Life Spikes for a very cheap kill.

- Far targeting no longer causes the game to crash if it cannot reach the track (bug fix)
Now gains a 4× attack speed buff for 2.5 seconds at the start of each round
| “ | Like a few other towers before it, the attack speed crosspath for Spike Factory has outshined the others. We have reworked the lower Spike Factory tiers to distribute this power more evenly while keeping high tier factories at a similar level of power. — Update notes |
” |
Overall cost increased by $200 (due to cost changes for previous tiers)- Base spike factory rate increased ― 2.2s → 1.75s
- 0-1-3
- Rate reduced ― 1.32s → 1.4s
- 0-2-3
- Rate increased ― 0.99s → 0.98s
Smart targeting now places spikes as far back on the track as it can, rather than directly in front of the Bloon closest to leaking (undocumented)
- Start-of-round attack speed buff duration increased ― 2.5s → 3s
- Spike Factory no longer can shotgun spikes for exactly one frame after spawning (bug fix)
| “ | Long Life Spikes can start creating a nice buildup of spikes in advance but most of the time feels fairly meh as a stepping stone into Deadly Spikes, a little price here is being shifted up to improve standalone upgrade value. — Update notes |
” |
- Upgrade cost reduced ― $1,400 → $1,300
| “ | This update we’ve finally decided to nerf Permaspike by completely removing the ‘Far’ target priority from the earlier Smart Spikes upgrade. We know that this loss will be incredibly painful to deal with for the many spike factory enjoyers out there, so we have also included a couple other minor QoL adjustments to the Smart Spikes upgrade in a hopeful attempt to offset this. — Update notes |
” |
- Reworked targeting options ― Normal, Close, Far, Smart → Normal, Close, Smart, Set Target, Automatic
- Smart Spikes: Adds a "Set Target" option, which allows to select the place inside the Spike Factory's range where the spikes go to.
- Smart Spikes: Adds a "Automatic" option, attempts to directly target the first bloon
- Removed "Far" targeting option
