Floor 1: hunter & squirrels
I used a hit & back off tactic, just trying not to get hit too many times, and avoiding any squirrels that are lit. collision detection on this guy seems off more than others as you can be clearly out of reach yet take a hit..
Floor 2: two grunts on floor and four or five on the top..
Use the grenades to whittle down the guys on top, each time I managed all but one, then took the floor guys out then use the rifle on any upper floor guys you may of missed
Floor 3: 5 grunts & a heavy..
I used grenades when the grunts where gathered, doing my best to avoid the heavy, and not getting cornered.. concentrating on the grunts til only the heavy was left, and only they pick up the club.. with heavies, I prefer to stay close, but out of arms reach so they won't charge, this way I can move in for a light hit (RT) and move away quick, repeating this until covers it's head then use LT for the heavy attack
Floor 4: 2 grunts and hunter..
get the enemies together, then lead them around the room as you walk backwards, chipping health off with quick punches or the triple hit. The Hunter was always last for me, he easily wasted half my health
Floor 5: Father-Mother, a heavy & about 6 grunts and Daedra..
This floor is ridiculous.. grab the grenades, and as usual try for grouped grunts, and try to avoid melee since there are far too many of them.. because Daedra is on your side it seems, so I just ran around, hitting when I had to until only the Father-Mother & heavy were left.. (which is where I got to 5 times and messed it up here..
Here you want to take out F-M first using the guns, and keeping a pillar between you and the heavy, going pillar to pillar when it charges.. for F-M you need to be shooting it in the legs til it falls or starts to run, keeping in mind where the heavy is, and move to the next pillar. Don't melee the F-M, just leave it to get back up, and start shooting it in the legs again - rinse & repeat til it dies, then kill the heavy in the usual fashion.
