UH.......so far so good the best weapons are: lead pipe ak-47 shotgun magnum lead pipe:go near the enemy by jumping,then duck while wacking him on the head to cause some serius damage.useful if enemies are crowding you.
ak-47:from afar,hit enemies in the head to cause some damage,then throw your weapon to cause some damage then use the lead pipe to kill them.useful against hordes of enemies
basically , once u unlock the sword , it replaces the lead pipe , that sorta becomes a seriously wicked weapon , however u can also use the hades rifle , always been my favourite , and once u finish the game 100% u get the N.U.K.E which really rocks and can instantly wipe out all enemies on screen woo =p
I like to SOCOM assult rifle. It's actually the best automatic gun in the game. Besides that I like the guass shotgun. I always use the SOCOM and the guass shotgun when i'm playing in hard mode. The sword is pretty beastly too, But you automatically have it once you get 500 lead pipe kills, so I wouldn't classify it as a chooseable weapon.
i would have to saw the sword coz u just keep back flipping into a wall and keep hitting the mouse and ull never get hit while u are killing a lot of enemies. although it does take a while with this strategy. Apart from that, hades rifle and gauss shotty and lazer cannon are pretty good at wiping out hordes of enemies fr example the third last room that u need 2 kill like 300 freaking enemies. i dont like da nuke coz it had a long reload and it just spoils all the fun coz it is so good.
