"I haven't gotten to the end yet but I hope there is a giant mega boss like a fat mafia guy with rocket launchers for hands and a mastermind alien is riding him down the street crashing down buildings."
You should have totally worked on GTA IV
I thought the final mission was a joke Lets Have a look at previous final GTA missons
Keep Your friends Close
End of the line
Each one of them were great missions However in GTA IV the mission feels so uninspiring .
All im going to say is if your near the end of the game finish it.
If not just play a diffrent game
