Road to gears 5

Hello. I can't wait to try the demo of this finde. in my case, I think it's going to take a lot of rounds or games

Upwards of 30 full games I would say. If not somewhere a little less, or more. Its a loaded question because it depends on skill, difficulty, and method of going about it. As well as like, what your average for a horde game normally is. But let's just
say probably a lot.

Quite a few, as im terrible at this game

Its not that difficult if you know how to play horde, as in what class to use & what cards should be selected.

A few dozen easily.

I would look at your past games and average out your kills per match and just add them to see.
