After causing so much trouble & upheaval it was time to get rid of the thorn in my side "CERBERUS"
An attack on their headquarters leads to a boss fight against Leng & you finally get the chance for revenge. Although be warned he is a tough bugger & it took me a couple of attempts before I managed to defeat him.
That was for Thane
Now I am all set for the return to Earth & the Final Conflict
