In "ShieldedInvader.cs", on line 10, there is this test for potential damage:

            if(_random.NextDouble() < 0) {

So this would apply damage when "NextDouble" returns a negative number. But according to the documentation page, that method returns "A double-precision floating point number that is greater than or equal to 0.0, and less than 1.0."

So that would mean no shot would ever hit.

You probably want a number other than 0 to indicate a percentage chance of being hit, like 0.6 for 60%.
