It may sound like a good idea to use a drill to take out zombies, but when you find that it has limited range and doesn't even result in a cool effect, you'll quickly drop it in favor of something better. You'll quickly find that not all weapons are created equal. But it's not just about combining random weapons. If you find a safe zone, you can access weapons in the weapons locker as well. You can access a list of blueprints and keep track of how many you have via the in-game menu screen.
Once you find the blueprints to a weapon, it's automatically stored in your inventory. Some are even conveniently located right next to the weapons they provide combining instructions for. Most of them appear on your map and are relatively easy to locate. There are 101 weapon combo blueprints in the game. However, before you can get some nasty combo weapons, you first have to find the blueprints to make them. It's never fun to have a throng of zombies surrounding you, only to have a squishy construction cone to fend them off. Some of those things on the ground can be used as weapons (just about all of them actually), and you can combine those weapons to make more powerful combo weapons that will have more durability than a normal weapon. Luckily, these two things have something in common. The first is that there's a lot of random stuff on the ground, and the second is that it doesn't take much for your current weapon to break over a zombie's head. When you play through Dead Rising 3, there are two things you'll definitely notice.
