I did what it said, I made it worth. I could recomend to limit the waves roster to really stressful waves where you can’t stop shooting* and waves like backstroke, surfing the wave, etc etc where you can miss the clean sweep bonus, because with a little patience you can get something like this.
saddest part was not reaching 600 keys
for example, the wave that costed me two lives, flower power with all UFOs.
My router hates me. Lost connection multiple times and lost 7 lives before getting to the point-of-defeat which was green bullet hell and my only weapon was 0 power level plasma riffle. Results are above. (I play on SSH, also this was the longest mission I ever played in CIU) (Patience is key, literally)
I wonder when will these missions be launched as standard mission that could be found in planets and possibly stars? Also I did the prototype mission in Superstar Hero, a mistake which cost me the remaining 3/10ths of the run. The enemy queue came with lots of chickenauts and I was annihililated. I did get over 500 keys though so it was far from worthless however.
I can’t believe I made it through Concentric Triangles (I’m not spoiling further content in this wave) with accidentally collected Vulcan Chaingun, losing only one life (and it was because I got greedy and try collecting a key, after I have destroyed most of the wave).
