This mod adds ability to aim by pressing right mouse button.
You can also run/walk while shooting/aiming.
To activate first person aiming on sniper rifles/rocket launcher, use "zoom in" button while stopped.
With melee weapons hold "aim" button and attack someone to activate 'classic controls' camera.
You can also reload weapon, while aiming press "R" button to reload.
Hold "G" to throw grenade or molotov. Or hold "G" while aiming to make instant grenade throw. The more you holding "G" the longer throw distance will be.
Press "Backspace" to remove current weapon.

GTA 3 v1.2 allows to aim with right mouse button, bug when other peds can't shoot was fixed.

Installation:
Copy CLEO and anim folders in your GTA Vice City root directory. If you don't want new animations for player, don't copy ped.ifp. Ped.ifp fixes weapon bug during 'run_back' animation.
Make sure you have latest CLEO library installed from http://cleo.sannybuilder.com/cleo4/CLEO_VC_setup.exe and gta-vc.exe version is 1.0.
Open data\gta_vc.dat.
