Thanks! Also, NEWS FLASH.
Yellow beams don't give a shit about your shields. Y'know, just to mitigate the fact that green beams bounce off now. They also hurt more, as you can see, since it hurts enough to trigger the red screen flash. The good news is that they don't damage your shield at all. Also...
Spread shot is a reality. The implementation of it went amazingly well; the very first idea and try i had, and it worked perfectly. It's an extremely powerful upgrade, even with the massive debuff in damage (-5 currently) it gives you. The shown configuration (all turret upgrades + 4 skillpoints in turret damage) was easily able to plow through level 4 without even touching the front guns. Unfortunately for you, the upgrade is really expensive, and getting it that early will probably cripple you horribly. Why? Because if you take that huge damage debuff before being able to support it (i.e. dropping below 7 is bad news, below 5 is a death sentence), you won't be able to kill the enemies properly. Which reminds me, it should be possible to sell upgrades again, in case you find yourself hitting an impasse because of poor upgrade choices.
