kind of bs that I spend a lot of time upgrading the factory, outpost, etc., and then there is an attack that is too hard to beat. Because I can't upgrade the outpost while under attack I have to just cede the area...what a waste.
On the final boss if you park your copter about an inch above the "S" in Score you won't get hit by the blue bullets. You'll take some damage from the pink bullets but only 5 hit points each. With the frag you can park there are beat the final boss without even moving!
Not too bad, kind of fun. It is annoying though when you are in a level and it switches back to your handgun. Seems to happen if you're in the streets and then go in the building and vice versa.
