I wonders that Weapon game finished and no winners there, xD
But some "weapons" that wasnt at list:
1) Fists(and they real deadly weapon if using with fightstyles);
2) Detonator - I think that weapon cos using separate data from Satchel charges(and appears only after using satchel);
3)Grenades - not found at list too;
And to Cage: game wasnt ended twice when wrerke and exotic repeated too. they changed weapon and game continued... before
