Im not even sure if this game is on the the sight, but here goes!
SV Infinity 1911: Starting weaopn. MK-23 SOCOM: At the top of the 1st building and then to the right on second level. Desert Eagle: Beat Hades prototype once. Dual Walther P-99: Beat third level. Dual Beretta 92FS: On a rooftop about 2/3 of the way through first level. My guide: If you start the level, go on top of the building, and go right, keep on the top of the buildings until you see the brown building. Next to the brown building is a grey building, and next to it, there should be a pink/gray colored building. The Berettas are on top of that one. Dual USP: Beat first level with 150 kills. Intratec AB-10: Beat first level. HK MP5K: Stinky Bean Survival with more than 100 kills.This is good Steyr TMP: Beat second level with 175 kills. Dual Cobray MAC-10: Beat fourth level. Dual Glock 18: Zombie Survival with more than 200 kills (that's what i did, cuz 100 didn't work... Dual Micro UZI: beat fifth level with 225 kills.these rule HK G-36: Beat second level. GIAT Famas: Head due right and don't jump from start of fifth level. Once you drop down go left. FN FAL: Beat fourth level with 200 kills. (Takes Magnum rounds.) Striker 12: Beat fifth level. (?) Benelli M4: Head right from start of fourth level until you hit a tall wall. Use platforms to get over it, drop back down as soon as you can and go left. Pancor Jackhammer: Beat super survival with 40 kills. M249 SAW: Beat third level with 50 kills. This is fricking hard. XM 435 super mags: Beat level 6 with 75 kills. NOTE:This isn't very easy, but it isn't the hardest either. However, it's the second-best weapon in the game (after the SAW). will make most of the other levels incredibly easier, especially the survivals (as you start with only pistol ammo, which these use with the damage of the deagle or FAL.) I suggest not getting them before anything unless you want to kinda break the game
