That particular Hulk loses a little health to pop out raptors, but it regens the damage back, it is a bit faster than a kevlar hulk but a bit weaker than a normal one, still can cause problems if I cannot focus on killing it as it regens the health back.

Pretty much yeah, usually a automatic rifle can deal with it, but unless it can be killed quckly it just constantly spawns the raptors like a screen for its advance.

Grenades are another great option as the shrapnel rips things apart if it is close, with I think it ignoring armour if i recall, bombs are trickier to use as it is a lot heavier, although i recall it was fun dropping off a barrel bomb at a fungus nest once.

Usually a trip to a mine for raw materials and a few lab runs should get materials last I played.

I seems I pick my molotov targets carefully, as I have safely clear a small town of all its dangerous foes by luring a large group into a building and lreaving behind a tactical "molotov" in it, setting it on fire and the resulting noise drew the rest of the town to the barbeque. But true, unless used underground Molotov's can be very dangerous.

Speaking of fire, I have escaped a frog mother's grasp in the early game by lighting a nearby bush with a zippo lighter before as it has a chance to run away in fear of the flame.

Only thing I don't like about carrying acid, is running into the acid blood and acid immune enemies, but otherwise yes the acid does do damage as I know I like to keep acid spewers alive to thin out the enemies by getting them between the acid and myself and especially with it keeping the goods intact is a bonus over the wild nature of the flame. Bonus for getting yourself acid immune boots and or gear and really using acid to its potential
