Firearms are available in Dead Island, but are much less prevalent than melee weaponry. Capable of dealing extreme damage at long range or up close, firearms are useful to any survivor — although ammunition is extremely scarce, particularly for the more powerful shotguns and assault rifles. The first firearms require a minimum level of 10 to use. It is possible to obtain a revolver as a quest reward relatively early in the Act I, as well as fifteen rounds (that's without an ammo loot perk, like Purna's Providence) in the front seat of a police car that overlooks the front entrance of the Royal Palms Resort from a distance (Note that this ammo will respawn when you leave the immediate area for a period of time, just like any other items). Firearms enter the game in force during the opening of Act II, mainly in the form of handguns with more powerful weapons becoming largely available as the game continues.
A mod blueprint exists for each of the three ammunition types: pistol ammo recipe, rifle ammo recipe and shotgun ammo recipe. The pistol and shotgun ammo mods are found around the Police Station in Act II, while the rifle ammo blueprint is received as a reward for a side quest in the Act III. Enemies using guns will also frequently drop a box of ammo on death, appropriate to the weapon they are wielding. Rarely these ammo packs can be found in the world in re-lootable sites (weapons stockpiles and armories). There are also mods to add damaging effects to one's guns, like electricity and poison damage.
All four survivors are capable of using firearms and obtaining small bonuses through skills, with Logan receiving slightly more than Sam B or Xian Mei. Purna, being the firearms specialist, receives the largest number of relevant skills and is capable of unleashing huge amounts of ranged damage — as long as her ammo holds out.
