I still think it was dull, my and brother were like "its shoot in the eyes, climb, repeat and repeat... and repeat" after having such a terrific fight with the scorpion-zombie thing (the one that grabbed you like a rag doll and then climbed up from the depths you had already thrown him into and fights with you going underground and all) I was dissapointed with that fight with saddler, the moment Ada threw the rocket launcher I didnt hesitate to end the battle, it was either do that or do the shoot eyes - climb sequence a dozen times, very few strategy needed, it didnt matter to have saved all the big guns for this fight, you just needed a shotgun and enough ammo to end it, the scape in the jet-ski was totally awesome though
I dont remember who was tyrant, it wasnt the scorpion zombie thing, was it? because thats honestly the best boss fight of the game I can recall now
