Quake 2, Lower Palace, Upper Palace and Outer Court Secrets Reprise (All Secrets Found)

Difficulty: Hard
New weapons: None
New items: Super Adrenaline
Secrets: 16 (6 in Lower Palace, 7 in Upper Palace, 3 remaining Secrets in Outer Courts)

The longest video of the playthrough, as it covers the whole Palace complex. Wide corridors, traps, lots of enemies - this takes some time to wipe it out.
First of all I deactivated the red force fields, so I backtrack to the Outer Courts to grab the remaining secrets. Two of them was mistakengly missed, the last one became accessible. Wait, what was the Red Key in the Outer Courts?
Well, this Key grants you access to the last item of the game - Carmack's Head in slime secret. This head is called Super Adrenakline and it gives you 6 additional Hp to the maximum health bar.
Really, the biggest amount of health is 142, but I failed to grab some Adrenalines during the game.
As communication system is successfully shut down, the rest is quite simple to say - face the Makron itself. Let's see what awaits me!
