I only finished off one more area in Halo 2 tonight, though it was a bit of an annoying one. Slightly twisty corridor, drop down a level, slightly twisty corridor, drop down a level, slightly twisty corridor, drop down a level… It only got interesting at the end, when bigger firefights erupted in more open areas, though the Flood continue to be annoying enemies.
Oddly enough, despite preferring Covenant weapons and playing as the Arbiter on this level, I found myself mostly using human weapons this time, since there was far more SMG ammo around than anything else. Since you can only carry two different types, I’ve been trying to stick to having one long-range, fast-projectile weapon for sniping and flying targets (e.g., beam rifle, carbine), and one rapid-fire, larger-capacity weapon for general use (SMG, needler, plasma rifle), switching out the long-range weapon for others as needed (e.g., the plasma sword is good against the Flood-infected or Honour Guards).
