The percentages given here in LB are approximate; the actual game uses a formula that is too complex for us to work out, but is a function of Player Level and Health of both bases. Bases full of well-upgraded turrets and buildings should show a better boost than the below which is taken from the upgrade screen and is smaller than the boosts in the player level gauge and player file. The percentage in the LB column is added to your level to get your new one for combat.

If the Generator is destroyed, these boosts fall back one Level until it has been repaired.

[Defense Level] = [Player Level]*(1+[Level Boost]).
Example: L100 Player, L9 Shield Generator;
100*(1+90%) = 100*(1.9) = 190.
Example: L100 Player, L9 Shield Generator HQ, L9 Shield Generator A1;
100*(1+90%+90%) = 100*(2.8) = 280.
Example: L100 Player, L11 Shield Generator HQ, L12 Shield Generator A1;
100*(1+136%+200%) = 100*(4.36) = 436.
Example: L100 Player, L9 Shield Generator HQ, L14 Shield Generator A1;
100*(1+90%+300%) = 100*(4.9) = 490.

Shield Generator

Reaching the Aurora-1 outpost, located in this frozen wasteland, will be difficult. Most of the ships we're sending won't make it back. Get the perimeter secured and the base operational. We're still investigating, but we've intercepted some Maar chatter about a...a shield generator.
