I brought this zombie thread back in case the police start to investigate what killed me. Please pass this along to them:
Leg extension, 3 sets of 50 reps
Seated Hamstring curls, 3 sets of 50 reps

Squat/Deadlift Combo - Set of squats followed immediately (no rest) by a set of deadlifts with the same weight
Sets went like this - 12 reps, 8 reps, 6 reps 5 reps - floor

Sled Pull - Frontwards/Backwards/Hacksquats
Pull sled strapped in (like a forward sprint) 30 yards, unclip harness then pull sled backwards to the start (30 yards). Immediately drop to hack squats.
Weight increased with each set. 5 sets. Legs gave out twice on the return and I hit the floor.

Leg Press. Well for those that know I train legs pretty heavy. By this point I could not leg press more than 225 pounds so I finished off with a little calves and then limped out...
