Finally, after 200 downloads of the original, here's the first update of Quasar E77 (Click "Read More" if the full list doesn't appear):
The four heavy cannon turrets were redesigned from their previous minimalistic white sphere style, to roughly resemble the drone from the movie "Oblivion"; some rail mass enhancers were added to the hidden docked entity which holds these "free-floating" turrets in their diagonal orientation.
Reduced AMS turret count from 30 to 10, out of performance considerations.
Added four laser turrets.
Rebalanced the shield system (the Weapons Update introduced changes which made this station's net shield recharge negative).
The new net recharge value is 505,000 HP/s, making the station durable against high-DPS attacks (capacity remained the same, 33mill).
The reactor was substantially buffed to ensure power balance when all defense systems are at max consumption (from 1.4mill to 2mill e/s; size-range unchanged).
Reduced chamber sizes (the Weapons Update halved the necessary number of blocks per chamber for a given reactor level).
Reconfigured reactor priorities (they were previously neglected and left in the default ranking).
Fixed the logic of the elevators that lead to the top observatory.
Added another discoverable secret, an animated one.
Added extra exterior detailing where it was most needed.
Added extension arms to two of the USD airlocks to facilitate the docking of larger ships.
Few other minor miscellaneous fixes, modifications and additions.
