The Steelmen started well a goal up on 4 mins, Rueben Marshall doing all the hard work but it was even on 7, Campbell with a header unchallenged.
Gibson put the Royals ahead on 17, before a third was added on 34 both goals could have been stopped. 3 - 1 down at the break.
Second half Corby played better a couple of god touch and confidence grew but again a lack of tracking saw the host make it 4- 1, Lekuti with the shot.
Corby pulled one back thanks to Ben Challenor with a rebound from a Widdowson free kick. Thats how it ended but Jake West did save a penalty in added time .
