This is the most easiest mission of all:
An anonymous citizen is having problems with someone who owes him money and wants you to sort him/her out! You'll need some speed, strength and a weapon, but all you have to do is attack and leave the person involved (Congenial ). You earn 10k for your troubles, costs 50 energy though.
This is very simple. An anonymous citizen has a problem with the FBI; two of his hackers have been tracked! You must infect the FBIs data systems and delete all the logs of their activates to clear them.
Basically go to items, and click 'use' on your firewalk virus. You then get 100k. Simple eh?
There are a few parts to this mission.
To get through the first obstacle, you will need a set of bolt cutters(available for $25 in El Cascado), and beat a photographer in Apartment 19. Once you have done that you will get an event saying that you have found photos on the photographer's corpse. Send the photos to Anonymous  to proceed.
Anonymous will message you, telling you to fight George . After you beat him, you will receive an article. Send that to Anonymous .
Some time later, you will receive a message from Jefferson , saying not to interfere with his business. You will then get another message from Anonymous , telling you to attack Jefferson.
After some server lag and 150 energy, you will receive $500,000 from Anonymous.
This is very hard, an anonymous citizen is having problems with his wife, and you must attack the man who's having an affair with her!
All you have to do is attack and leave the person involved (Prime ). You earn 800k for your troubles, easily worth the 50 energy.
Anonymous wants to try an old game he used to play with you. Foot Russian Roulette is where you get a smith and wesson revolver and load its barrel with a single bullet, spin it and shoot yourselves turns. Whoever shoots themselves loses. You need to bet 50k on the outcome, you win anonymous's 50k if you win though. All you need to do is click 'shoot'.
This is much easier, an anonymous citizen is having problems with a woman in his business and wants you to sort the nark out!
All you have to do is attack and leave the person involved (Superior ). You earn a cool 2.5 million for your troubles, mansion time!
Anonymous has a job for you; he wants you to blow up the skyler building. First you have to get some C4, it will cost you 10k from the man at TC docks (go to the bottom of the docks page). Once you have the C4 mail Anonymous  and he will tell you where to go. Go to the city page and find the skyler building. The elevator is broken, so take the stairs, kill the guard (don't pay him)and plant the C4. Once you leave/hosp the guard you'll get a message from Anonymous saying the building didnt blow up right, but it wasnt your fault. You get $350,000 for it.
This is a bit harder; an anonymous citizen is having problems with a grass who wants to shop him for his drug dealings and wants you to sort him/her out!
All you have to do is attack and leave the person involved (Neato ). You earn 200k for your troubles, easily worth the 50 energy.
