I can`t get any further, cause the hacking mini game seems to be impossible. I always die in cyberspace.
What am I doing wrong?
When buying disks, stick to just one or two types. It's better when one or two weapons are more powerful then all three being weak. I like to use Wedge for focused fire power and Pulsewave for clearing swarms.
Use both hands. Simultaneously aim & shoot with the mouse while moving using WSAD.
Always have some single-use software for emergencies. I like to use Datashield. It's cheap, and effective for escaping out of tight spots.
Keep recharging Focus. Leave cyberspace, recharge Focus, go back in. Everything you've destroyed will stay destroyed and is not going to appear again.
