This is a Nailgun Mod, which corrects the position of the Nails for Nailgun and SuperNailGun.
Originally, the Nails appear on the lower edge of the screen instead "out of the mouth" of the Nailgun.

This Mod corrects it.
(see screenshots)

Even, when you look straight in the sky, the nails still appear in the corect position now (for NG and SNG).

Special Thanks goes out to Sajt.
He told me what to do.
I simply followed his words and want to share it with you.

Greetings,
Seven
