I was having a hard time getting a single shotgun hit to kill the soldier in the area with the lava,
why not just shoot twice then? :P
you can manipulate luck to get explosive shells but it will be harder because your tek arrows are not full.
I did know about the arrows, and as you show with the knife on the high priests on level four,
that sucked, use 2 grenades on the first one.
you can only get critical hits with arrows if you're moving when you shoot, but they don't work very well for some enemies, like high priests. on some enemies, the knife can be even more effective than critical arrows. the tough moron high priest on level 5 guarding the cat key takes 14 tek arrows but dies with one knife.
(I think that was the maximum it went, it may have been 225).
with gameshark you can get a maximum of 7777 HP tek armor. if you try to take one more it flashes 7802 but goes back to 7777.
the spirit tokens (or mortal wounds) were the most useless items in the game..
