Just wondering if the events will eventually disappear or if they stay for good once you activate radnet?
Also, do you have to get the best score to "pass" the event? I tried the one where I have to kill the soldiers by jumping off the roof and doing an attack but noticed I didn't get a checkmark until I killed all of them, is this the way all the events work? --- If a woman sleeps with 10 men she's a slut, but if a man does it.......... He's gay, definately gay.
Once a radnet event unlocks, it stays unlocked permanently, so as long as you have an internet connection to open all of the available challenges, there is no time limit.
To pass an event, you only need to get the bronze score. For the first few events that use the hammerfist divebomb attack, you have to kill all of the soldiers to get to round 2, and you can only get enough kills for bronze by getting to round 2.
