Had almost the entire map covered in technological goodness, had reached 300 on the emitters on survival...was going strong...Shockwave...why have you failed me? Why?
Do nothing but invest in the shotgun, strength, and endurance. About 20 points in agility will help, but put the rest into strength and endurance. I beat the entire game with nothing but these three things. The TMP helps in Hell, but lvl. 1 is fine.
