I've finally reached the end of Depot A. It took a while, because I was 1 (one!) point away from being able to craft a near-perfect set of Depot A armor (mutated dog leather, high-density foam padding, and blast cloth, all q50ish) but couldn't find any deep pies for sale, so I went exploring and killing until I managed to level up. Thanks, Junkyard Surprise nerf. Also, we once again contemplate the silliness of not being able to construct anti-acid armor until we've already spent a lot of time wading through oceans of it.
I'm really enjoying the spear so far, or as I prefer to call it, La Lance du Fromage. The extra reach is more useful than I originally suspected (anyone remember how mutated dogs could be like 1cm out of melee range while you were blobbed?), and the melee blocking aspect is actually very noticeable, especially after obtaining Spear Guardian. Once I get Iron Grip and Fend and start one-handing the spear, I'll enjoy extremely potent melee damage reduction when not incapacitated.
There have been a lot of great moments with the spear. I once had the opportunity to perform a spear throw against a big mutant standing something like 8 grid squares away. The hit chance was exactly 50%. (I'm still carrying just the one steel shock spear.) I took a gamble, threw, scored a critical hit, and he went down in one shot (from full health) suffering a total of -357 damage.
I also enjoy throwing molotovs absolutely everywhere and for just about any reason. They're obscenely helpful in the early stages of the game for blindly eliminating mines in suspiciously open areas, knocking NPCs out of stealth, and of course noise attraction, area denial, and just plain damage.
