My weapons do zero damage help!

Some weapons you can put onto of each others so that would make them fire. Some will erase the others of it so be carful what ones you take of

No damage, mabey this is because they have body armour or something like that. Check your sccuracy rate as if it is low then of course you will have less of a chance

All I could go with is interfearance and % of shooting. Sos I cant be anymore of a help

Edit: Other then them they could just have equpited an avoid card so that might make them miss

trust me the gun your using sucks dont use it! u have cards in the game that can be supplied to your gun like for e.g. aim. you can make this work by equipting the card on the gun in the box. it should say supplyment. so the next time you counter or get the same gun and equip it on the same gun in the box it says load. then when snake shoots the target the aim will be added to it.

trust me its not about armor or aim or anything like that. Musachi 86 had it almost right. If you equip a weapon, or equipable item or character card (snake from MGS2 is a good one for this,) then dependent on the color of the arrows and which direction they point, the adjacent equipment cards have their stats adjusted. Red up the attack power but lowers defense, blue raises defense and lowers attack power, and Im not sure what green does other than up reaction percentage. MGS2 Snake is a great card to equip because it has red arrows on every edge, bumping up every equipped card adjacent to it.
