What I can bot map?

What happens is that just today I realized that by picking up bonus boxes on the map 1-1, now I only have 50% of the content.

I'm level 8, I bot a week and I have a Leonov, 2 Iris, 8 LF3, 3 shield generators (10,000 U) and 6 generators (2,000 U).

I want to continue to achieve more bot elite.
Which map do I do?
Help please, I tried to do in PVP 4-1, but I kill all the time.

bot aliens on X-2 everyday :awesome:

you premium: bot aliens and boxes in x-1, x-2, x-3, x-4.
you not premium: bot boxes invisible in x-3, x-4.

ur level is hght to loot bonus boX in x-1.. U should go x-2 or x-3.. if u listen my advice , u'll go to x-3.. x-3 is better than x-2.. U earn much uridium in x-3..

Bot on x-2 because you can flee if there are to much enemies.
