This was originally intended as a knife. Million made the models/skins as such, i just copied one model over to make it work fully as a handgrenade (knife is untouched in this install). Dark_Soul made me laugh by posting, make it a grenade and add a sound 'oh no, the strap broke!'
..so i did just that. Here it is, in all its glory! WATCH OUT FOR THE LCD TV! aka skulk.
Installation is just to the ns/ directory: the directories should place everything you need. BACKUPS ARE INCLUDED! The model p_gr.mdl has been replaced, but a p_gr-bkp.mdl, the original, has been placed beside it.
Sounds added were the grenade_throw, and grenade_prime (two versions of the prime are available: default is 'WII! Grenade!', second is simply 'WII!').
Enjoy! And thanks Million for the great models and skins!
