does anyone has a NullReferenceException in RandomTests?

maybe you should replace var with dynamic in test cases code,cos I keep getting "object does not contain %FieldName%" while everything works fine with dynamic on my pc in vs debugger.

python 2.7 code passes all tests but fails due to the timeout issues when I press Attempt

check this test case for C#,please.You are upgrading marine`s damage twice,so after the second upgrade it will be 12,not 11.
public void _0_SingleUpgrade()
{
IMarine marine = new Marine(10, 1);
Assert.AreEqual(11, new MarineWeaponUpgrade(marine).Damage);
Assert.AreEqual(11, new MarineWeaponUpgrade(marine).Damage);
}

Fix your test cases,please.When i run my code i got this message:
Expected:"Ths wbst s fr lslrs LOL!".Isn`t 'O' a vowel?

Could you add some examples into description of this kata?If the Name of person is "Name"-he is a Spy.In all other cases he is a Police.Did i understood this kata right?

Thanks for help!

you should write
throw new ArgumentException() ;
to throw it.Check your code-maybe you wrote
throw new ArgumentException;
without paretheses or
throw ArgumentException();

when i run my code i got this: Error: Command failed: /tmp/csharp116030-19-2w5u9y/code.cs(9,62): error CS0029: Cannot implicitly convert type System.Collections.Generic.List' to System.Collections.Generic.List'.
WTF?

what value for pi should we use?
