pyrotechnics medal is screwed
I use the last shoulder weapon(not giving spoilers) on the first level (one on the mini-boss, one on the boss) and it didn't work so i use the second from last shoulder weapon (still not giving spoilers [one on the mini-boss, one on the boss])
I think The enemys should shoot a variety of different colours (e.g:yellow shoots green, green shoots blue, blue shoots purple and I haven't got past purple) and if you match a colour with the bullet and enemy the bullet will do double damage (Just a suggestion) :)
