Some time ago i watched a YouTube video from GTA LCS, which was recorded from PS2.
I saw Toni sprint with a two-handed weapon, and i was like "What was that?!?".
After finding out that LCS uses VC engine, i decided to enable sprinting with two-handed weapons in VC.
And it was easy as 1-2-3, the best part is that VC natively has support for sprinting with every weapon.
All i had to do is just simply change the animation names the game calls for and add the sprinting animations!
And that's how, this mod was created. Now you can sprint with two-handed weapons! Enjoy!
