I am somewhat near the end of the game and am in one of the latter stages of Hell facing off against the Guardian. The Guardian is a very large dog-like beast with five little "seekers" who fly around the area and protect the Guardian. According to the strategy guide, if you shoot and kill all of the seekers, the Guardian becomes vulnerable. I've successfully killed all of the seekers (countless times) and then started to unload on the Guardian to no avail. Shortly thereafter, the Guardian sprouts new seekers and the whole process starts all over again. I've even tried using "god mode" and "all weapons/all health" codes which work, but don't seem to help kill the Guardian any more so than without the codes. I've even tried shooting the Guardian with the BFG gun about a dozen times (and it should work, as the cross-hairs turn to red when placed over the Guardian). What am I doing wrong here?
