Cheat Engine

[HitIer]

I mean, I've seen a lot of people putting up extra files and stuff, add-ons that go with Cheat Engine. On it's own, is Cheat Engine capable of making complex programs like aimbots?

Yes, you can make aimbots with cheat engine.
Do a hook at a place where you have access to all player objects to build a list of coordinates
Then at an often called routine (every frame) do a injection that goes through that list and checks which target is closest to you, or the center of the screen.
Then calculate your horizontal and vertical lookat axis so your crosshair is pointing to that specific target. (might need to add a small height so you shoot at their face instead of their feet)
And then optionally execute the "shoot" command as well (execute it directly if you know where it is (ultimap) or just change the keystate of the left mouse button to down for as long as the target is alive)

I recommend combining this with a dll you write yourself to do some of the math and list keeping for you like I did with the unreal tournament aimbots for ce, but without it is possible as well
