[󠀡󠀡]

[Vigilante]

think i got one from the greg factory map ( snow area 2)

[REAPER]

I got one in snow area 4, the resume soldiers mission， in the box near the soldiers (finish the mission and open it). More often appears in last map. BTW any small boss can drop it in the recycle day.

also got plenty from doing the infinite defence mode (left wave 8 so you don't need to go really far)
