Hi has any 1 completed the bit where you got to kill the guy on the boat withwout beening seen? I'm finding it really hard to complete. Is there a good way of doing this without beening seen by the guards? I can kill quite a few of them bt then the other guards notie me n once youve been seen you got to start again. So I was just woundering if any 1 has complted this bit and can help me kill the guy on the boat you got to kill plz?
