Worst SN start is a little harder to be sure of than the best. There are so many options. Here is one of the lower end starts but not technically the worst (click bait titles and all).
Tick 1 -
Do not cast SA
Build 8 additional eships (total: 108)
Build 250 CF
Disband all fleet (not eships)
No science (literally the opposite to LG)
Send out all eships (to not have the same cash decay as other players will get (a lot of non organised and semi organised players will do this)
Tick 2 -
0 and 1 tick planets hit
Build 1 iron planet and 1 endu planet to FB
If leftover materials make HF
Tick 5 -
CF hit and you produce about 1.2-1.3k cash (Minus current cash delay)
Tick 6 -
Send final 8 eships
Literally the shittest Day1 that I could think of.
Also you have to hope you don’t explore with someone else because it has come to my attention that people double send. (In case you were wondering, they use old map to bypass one per family send).
