bgillisp said:True, but I found that by the time you get to plasma guns and such the enveloping feature of those weapons made a mnor 3 point reduction (10 at most with the best shield) so insignificant that it wasn't worth it. I usually always had the best armor in the game, and 3 points of 3600 meant nothing to me. Yes, there is vunerablilty to ion pulse cannons, but I found the computer AI was smart enough to put powerful weapons that took out the shields before firing the ion pulse cannons anyways, so was a moot point (lose my shields before they fire the ion pulse, or lose my armor then they fire the ion pulse. Either way I'm probably dead). And any human I ever played against did that as well.
Usually, if I found I needed shields I traded for them, but I focused more on killing the enemy before they could board or destory me. Plus, you can't have shields with hard shields (reduces all damage by 1/4) on the ship, which I got 90 - 95% of the time by the endgame.
I'm thinking you havn't played for a while. Hard shields work with shields and reduce the damage by a further 3 points and allow the shields to function while in nebula and block shield piercing weapons. There is an energy absorber tech that absorbs 25% of the damage, however this can be used in conjunction with shields. You are probably thinking of the damper field which absorbs 75% of damage, but does not work with shields.
Plasma cannons do a pretty huge amount of damage, however they are a lot further down the tech tree than class 3 shields, and by then of course those shields will have a pretty small effect. Class 3 shields are important in the early game, they make your ships a LOT tougher to low level weapons.
I've tried moo once of twice, but the interface always puts me off since I started with moo2
