Hgauss buffs:
-10% damage increase to separate itself from the IHgauss (does less damage, but has more range and no damage drop-off)
-Ammo count increased to 6 shots per ton (from 4)
-Ammo price decreased to 1600 per ton (From 2100-something)
These, combined with the previous increase of the damage-dropoff range, are part of Operation Make-The-Hgauss-Not-Suck, a highly necessary project given that one of the new assets for 0.5.4 was kinda centered around 'em.

Also, hooray for the return of the Thanatos
A!
