Spawn Shield

Info
This upgrade increases the amount of time your tank is invincible when it respawns.

Rare
+2 seconds respawn invincibility

Epic
+3 seconds respawn invincibility

Strategy
This upgrade is similar to a health increase in that it increases your survivability, though it is more situational and potentially more potent.

Opponents will not always realize you are invincible and will waste shots on you, buying you additional time for yourself and teammates.

Pair it with speed upgrades like Afterburners, to help cover ground and get to where the fighting is thickest.
