If you use the shoot buttons to use the pick axe they will go an infinite distance and do 50 damage each
If you use the melee button it will lunge into a nearby enemy, swing both axes and do 100 damage.
Also the ice picks are an actual weapon so you can drop them and pick them up again.
Some super hardcore hacker mod guy could probably get it to work online.
Doubt it as its not in the multiplayer files, maybe on pc it could be shown to you as that animation but others who you would kill would see the weapon it would be :embarrassed:
