im currently unable to complete challenge 4. i cleared 1-3 within about an 2 each. less then 30 min for 1, less then 40 min for 2. and just a touch under 2 hours for 3. and 4 is looking impossible currently.

currently grinding ip to buy 1st 2nd generator.

You may lack some generators for it to be doable.
It's normal to not be able to clear every challenge directly, you can farm a bit of IP and enjoy the new perks you unlocked with the challenge, then try again after buying a few upgrades !

4 is wall, 8 is minor wall and 9 is big wall. Just farm IPs, buy upgrades and generators untill you hit "cost wall", then bank some IPs (some upgrades gives multipliers based on your current IP) and try c4.

It took me over 40 minutes to finish it and i think it was about slowly pushing promotions to lvl 50.
