Great game, holds up well against other imsims. Really flexed my creativity, and it wasn't until I realized that I wasn't going for a pacifist run that I really opened up.

Goodness, I already feel nostalgic for the early levels.

If you're playing on Strict, enemies regen their health fairly quickly, so it's a game of "you come at the king, you best not miss." Which actually isn't THAT difficult; you can do a lot of damage with a fair bit of preparation. This ain't your pappy's wave shooter, you gotta scout out your enemies, see if they've got any supporting healers, hack the healers, isolate your prey. Lock them in a transparent room of containers. May be tempted to scratch at the walls, make them know fear, but that'll activate their onboard shields, making it that much harder. No, the prison is the FINAL step in executing these lesser beings. The moment they glanced even the slightest hint that something was wrong was the last moment of their pathetic life. They bump into the box to get around it, boom. Box blows up, rest of the walls blow up, they blow up, you blow up, you load a save and take a few steps back beforehand, they blow up, you rush in with a shotgun and cap their head clean off, then cannibalize their "corpse" for that sweet, sweet fuel.

Lesser difficulties you'll have great success chucking boxes and explosive barrels at people, no tricks, edit: on strict+, I said they'd heal up by the time you can grab a second barrel, but that's only if they detect you first. I've been having a lot more success just by planning the tosses, timing them when they look away.

I also ended with well over 200 ego stashed away, so as long as you're not "wasting" it with excessive revives, you'll not need to fret too hard over currency. All in all, this is a great game worth your time and worth your mind.
