I have the scratch card and built the blam-bow (bow and arrow with dynamite) but since I don't have the combo card, I can't get the maximun hit points when I fire the weapon. My character is at level 46 and I still don't have the combo card for this weapon. Can someone tell me if I have to earn this card or is it hidden somewhere in Fortune city and if so where.
One thing I find annoying and I wish the trainer would address this is unlimited inventory slots so you can pick-up every object in the game so it's easier to build weapon combos when you find a work bench. As it stands now you have to constantly drop objects or weapons in order to make room.
There are quite a few weapon combos scattered around the city which CAN'T be acquired by leveling up. They are usually stashed away at secret location,OR can be acquired by scanning posters etc etc. There are game guides out there which can help you with finding them.
Here's one : Link
Unlimited slots would be fun but usually you'll find corresponding items for combos IN or AROUND a maintenance room itself.
