Base defense
Factory Defense and Guards
Build layered protection using walls, laser doors, turrets and guards. Pay attention to power: the official raid instructions tell attackers to shoot it out before cracking your vault.
What each defense adds
| System | Confirmed role | Practical priority |
|---|---|---|
| Walls | Advertised factory defense; perimeter walls appear in the tutorial | Close obvious access routes as purchases become available |
| Laser doors | Advertised defense; purchased during the tutorial | Check entrances and remaining open routes |
| Turrets | Advertised defensive equipment | Use alongside barriers; exact range and damage are not verified |
| Guards | Recruitable defenders with Rare, Epic and Legendary rolls | Read the in-game recruit offer before spending |
| Power | A target in the official raid sequence | Keep it in your defensive checks; do not assume walls alone protect the vault |
Choose the next defense by the problem
If players can walk straight into your factory, work on accessible perimeter and entrance purchases first. If the entrance is built but attackers still get through, review your available turret and guard options. If your teammate is leaving to raid, agree who will watch the base.
This is a suggested response plan, not a verified upgrade efficiency ranking. Prices, prerequisites and coverage can change with updates; the purchase offered in your current server is the deciding input.
Recruiting guards without guessing the odds
The developer explicitly advertises rolling Rare, Epic and Legendary defenders. That confirms those rarity labels, but does not establish their probabilities, guaranteed rewards, duplicate rules or a named guard tier list.
Before a roll, read its cost, the possible outcomes and any displayed odds. Compare that uncertain reward with a defense purchase whose result you can inspect. Keep enough cash for the next production or defense purchase you already need.
A higher rarity label alone is not enough evidence to claim a specific guard is the best. Compare the actual guard information shown in your game, especially its role in the approach you need to protect.
After an attack
- Check the status of your factory's power and vault using the game's current prompts.
- Inspect the route the attacker used. An uncovered entrance is a different problem from being outgunned after entry.
- Collect available production cash and choose the next affordable repair or defense action the game offers.
- Coordinate the next trip. Avoid both players leaving immediately if the factory remains vulnerable.
