At first I didn't knew what to do, so i had to read the mission briefing first. Then I had to buy the Ip lookup program cause I didn't have it at the time of the first three infections...
Now at this time the first 2 minutes had went with buying and understanding what was happening.
Suddenly 3 more systems were infected and I started to do my work only to realize that I had to set up a connection route first!
Moments after I'd set up my route 6 more systems got infected! Slowly I began to hack my first system but in the haste I forgot to use my proxy and firewall bypassers... By the time I was done with the first infected system I only had about 30 seconds to do the 11 remaining systems... I only got 1 other system before 10 other got infected!
Now with 20 systems infected I think to myself that it would have been nice if I have had a chance...
Conclusion: BE PREPARED!!!
