How long is the Alien Missile Acid effect?

[Nanaki]

Anti-laser fields reduce the damage of all incoming laser weapons (Progenitor beams, particle accellerators, lasers, and pulse lasers) by the percentage shown. Kinda OP, really, considering they go all the way up to 90%, which renders even the powerful progenitor cannon kinda weak.

My guess is that the anti-laser fields were designed to stop people from whoring lasers, as was the obvious thing to do in Star Wolves 1 and 2.
