fuck man does that mean i cant complete the game!!!!!!!!!!!
Well... as you say... you don't have any mission markers.
No mission marker would indicate that the game is over for you at this point.
I've played the game around 30 times and still find it interesting.
Do you have a friend that can copy a save for you to a card?
Else start over, and cool the cheats. If you do use a cheat don't save it.
The only cheat that is really any good is the Hydra, and that just for the purpose of learning to handle it in flight. But don't save it.
There is no real reason to cheat. All the missions are doable with practice.
All the weapons and body armour are available for free, if you look around.
The only thing you need to buy is property.
Offing the corner drug dealers ($2000 a pop) or
doing the sub missions earn piles of dough.
Firefighting gets CJ fireproof,
Burglary gives CJ infinate Sprint,
Taxi gets lots of cash and bonus' for doing them all in a row( plus gets nitro for the cabs after 50).
Pimping gets CJ cash.
Vigalantte gets cash plus 150% value to the body armour. (Not really useful.)
Doing jumps with the vehicles picks up cash too.
Finding the Gang Tags gets a weapons cache in CJ's Kitchen.
Finding the Photo ops in SF gets a weapons cache by the doherty garage plus $100,000.
Finding the Horseshoes in LV gets a weapons cache by the Four Dragons Casino plus $100.000.
Finding all the Oysters makes it a cinch to get girlfriends.
Keep playing and have fun. Just don't get too angry when it gets difficult. Take a rest and think over what needs to be done, and maybe a different way to do it.
Cheat if you want but DON'T save it.
