The crafting system sounds great
http://www.gamesradar.com/last-us-preview-joel-vs-fungus-zombies/Joel can pick up guns, lead pipes, shivs, and throwable objects for weapons, but they all have severe limitations. We're often short on ammo, weapons eventually break, and well aimed throws take time to execute, so ensuring that you have enough supplies on hand is an important part of winning a battle. Stealth is your friend, especially since the Infected are most easily overcome by taking them down one by one. If you have a shiv handy, you can sneak up from behind and perform a stealth kill. Though, our favorite method was to stagger an Infected with a flying brick then run up and club them over the head with our homemade, scissor spiked, two by four.
Crafting and upgrading weapons is also a big part of The Last of Us. As we mentioned before, when we weren't being attacked by zombified mushroom people, most of our time was spent scavenging for supplies. You'll find materials such as blades, batteries, bindings, rags, and alcohol laying about which can be used to create beneficial items, like medpacks and molotovs, or they can be used to modify your equipment. Joel can also pick up recipes to discover new items to create. One recipe we found allowed us to combine a bottle of alcohol and a rag to create a fire spreading molotov, which came in handy for taking out Clickers.
