HVM 004

The HVM 004 is a medium-damage semi-auto shotgun in. It can be good for taking out weak crowds of zombies (as most shotguns are) with its multiple flechettes. It has a low damage rate due to its shotgun nature, but makes it up with a relatively quick rate of fire, if the user can click as quickly as possible. The HVM 004 gets its damage is increased to 120. Because the 004 can deal 420 damage to its target if all fletchettes contact, this is a surprisingly good weapon in low and even mid levels.

And when Augments take effect, it can be a very effective mobbing weapon, rivaling guns like the Hard Thorn.

Design
HVM 004 is a semi-auto shotgun looking like a Browning Auto-5 with a flashlight / laser pointer (which are likely mistaken as pump handguard).

Difference on Mobile
HVM 004's gunstock of Mobile version looks more realistic, thus making it more proportional.

Trivia

 * Due to its look, HVM 004's capacity of 25 rounds are pretty unrealistic even if it had 2 magazine tubes like KSG. It's probably some sort of compression or nano technology applied for this case.
