The Alka Mod. 93 was designed and manufactured during the Yugoslav Wars to arm Croatian militias. Production began in 1993 and ceased around 2001, when IMP reorganized into HS Produkt. Since the end of the Yugoslav Wars, many Alka Mod. 93 submachine guns have been trafficked across Europe in the illicit arms trade, and examples continue to be confiscated by police in various countries, as is the case with other wartime Croatian submachine guns. 
The Alka was made entirely of metal and plastics and uses design elements from the Škorpion, Uzi and MAC 10. Unlike most other submachine guns of the time, however, the Alka was actually considered to be very well designed, much like the Zagi M-91 and the ERO submachine gun.
The weapon has a lightweight bolt with a short travel, which allows for a very high rate of fire; the rate of fire for the Alka is stated to be over 1,200 RPM. The charging handle is top-mounted and is very similar to what is seen on an Uzi or MAC 10 while the folding stock appears to be very similar, if not identical, to what is seen on a Škorpion.
- The Alka is considered to be one of the last, if not the last, Croatian submachine gun developments during the war.
