The Defense Matrix is the term for the impassible shield that surrounds a base that has been sufficiently damaged. It is totally impenetrable and cannot be destroyed or bypassed except by VEGA Siege fleets or Alien fleets, but is only temporary.
When 25% of a base's total cumulative health has been lost, the matrix will raise and last for 2 hours. At 50% or once the bridge has been destroyed, the matrix will last for 12 hours. If the base sustains 64% damage, the resulting matrix will last for 24 hours.
The matrix will, however, drop if the player whose base is protected attacks another player's fleets or base. It will not drop if another player attacks your fleet or if you attack a VEGA fleet of any type, meaning resource harvesting is still possible.
Additionally, a defense matrix can be purchased to raise by spending coins.
- There's an negatively associated stigma with defence matrix and are often mockingly called a bubble. Almost no player refers to them as defense matrix.
