Completing Alien Campaign on Aliens vs Predator (2010) with Grabs

Timestamps: 0:00 - Research Lab 12:36 - Colony 21:49 - Refinery 29:53 - Jungle 42:49 - Ruins Decided to play through this game with challenges or handicaps on the different campaigns. For this one, I wanted to try and beat the Alien Campaign using only stealth kills, finishing moves and harvests. Might make one where I'm only allowed to kill enemies from behind, other than the Predators. Speaking of the Predators, they were easily the most annoying aspect of this challenge, as you can only finish them with a grab if they're one hit away from death. It took about the seventh try until you saw the result in the video. Rules: 1. The killing blow on all enemies HAS to be a grab or harvest on the Weylan researchers. Kills from other Xenomorphs (notably in the Research Lab level) and that one Facehugger in the Jungle is fine. 2. Utilising normal attacks is fine as a set-up for a finishing move. 3. I'm playing on Hard (not Nightmare) because I don't hate myself that much. But I might in a future video once I put more hours into this game. 4. Disregarding any of these rules above will result in the level restarting at the previous checkpoint.
