It's just like any bonus on completing a stronghold/fortress. (25ss/45hh) You get a bonus chest at end - For 25s you can get hover tank, FAV and something else I forget. Normally it is medels as reward. I did about 50 25ss when I was below 30. I NEVER got Hover.

For E-Spectre it's the same but odds are probably even harder:

Kill a HH 45's. Click the bonus chest at end. Did you get it? Didn't think so.. Kill more HH 45's. Try, try, try, again.

You might win it first time. You may never win it. I am guessing (by how many have been getting it) the odd's are about 1 out of every 40-50 tries.

Again you may do 10,000 45s and still never get it. It's a ~40 sided dice roll afaik if that makes more sense. Your odds do not substantially improve each time you complete. "It's a roll of the dice..."
