@joannawww "You can graze enemy bullets by moving very close to them, but not quite touching them. You'll see a little spark and get some extra points for doing this."
You get bonus mission by shooting once on each card(an Ace) on every mission. Just look for a card in every mission and shoot it. 9 missions, 9 cards. I didn't understand this at first, kinda hard to comprehend for some which is fully understandable.
Would like it more if one could see the descriptions of unearned achievements. Pretty hard to complete all achievements if you don't know how to complete them. :-)
Very good game with challenging bosses and a great ending. I actually enjoyed failing multiple times over and over again in this game, even though it sounds strange.
1. Fully upgrade Pistol
2. Buy AK47 and fully upgrade it
3. Buy Gatling Gun and fully upgrade it
4. Profit!
Chainsaw is the most expensive weapon but also the worst imo.
