There's a simple objective to any competition, game or challenge: Make the other guy lose more than you do. So, here's a flash game built on that. Warfare 1917 is built around trench combat from the First World War, going from one stage to the next. Your task is to play through the (relatively short) campaign to the end, and having the greatest difference between troops lost and enemy troops killed. It's as simple as that, with no limitations on how you go about it or what upgrades you end up using.

Once you finish take a screenshot of the end of campaign screen tallying up all your scores and upload it onto here. You should be left with something like this: https://imgur.com/sE5sSaX Ties will be decided by whoever submitted their screenshot first.
With that done, good luck and have fun.
