Game Hints

Easy kills

After you kill the hatchet guy as soon as you start the game, go upstairs to the window. Do not jump out. Instead, take out your pistol and shoot the glass out. Then, carefully aim for the villagers' heads that are awaiting outside. There are three of them. If you kill all three, you can jump out and avoid any damage.

Good handguns

In terms of power, the Red 9 is the most powerful handgun. It has about power 6 or 8 when you get the exclusive upgrade for it. It has decent speed, and good capacity (20 rounds full upgrade). The Punisher is good for crowd control because of the penetrating rounds, but otherwise use the Red 9. The normal 9mm Handgun in the beginning is average, although it is best with headshots because the exclusive upgrade raises the critical headshot ratio. The Blacktail has no obvious weaknesses or strengths, and is a very versatile gun. The best handgun is the Red 9. Its power, speed, and lots of ammunition make it a very good choice. Fully upgraded, the Red 9 has about the power of the shotgun in every round.

Easy money

Once you gain access to the tunnel with the merchant beyond Pueblo, return to the farm area and wait for the chickens there to lay eggs. Exit and re-enter to begin the same process over again. After you fill your inventory, you can return to the nearby merchant to sell your eggs. White chicken eggs sell for 300 Pesetas, brown eggs for 600 Pesetas, and golden eggs for 3,000 Pesetas.

Get a five star rank with all mercenaries to unlock the Handcannon weapon. To get unlimited ammunition for it, fully upgrade all of the Handcannon's options. Successfully complete the game two times. The Handcannon will be available as soon as you start the game again for 0 Pesetas. It is a very powerful magnum, and will have unlimited ammunition. When you go to upgrade it in the merchant window, in the "Handcannon" update screen there is an option labeled "Exclusive". When chosen, the gun is upgraded with power identical to the Chicago Typewriter.
