The electrical boxes will pause for a longer time (a few seconds) and then you are safe to cross. As for the truck fight, the easiest survivable tactic is to use the cover spots provided by the large turbine enclosures.
I have beaten the game, but it was only after lots and lots of frustration. I'm conflicted, because when the game is fun it's SO FUN and there's nothing quite like it. But man, when it's bad it just feels cheap. There's little things, like the fact that the player can get stun locked by later enemies who have automatic weapons. Overall it just feels like no matter the difficulty the player is just made out of paper mache even with fully upgraded endurance and body armor. And speaking of body armor, it lasts for such a short amount of time I'm not even certain it needed to be in the game in the first place. The entire forest and cave sequences were an absolute pain in the butt. I'm not sure why I'm fighting suicidal eagles in a tech-noir dystopian action adventure game.
The story and presentation are awesome, I love the music, and the game as a whole is quite fun at least 60 percent of the time, but it just felt needlessly frustrating for a lot of the experience. I hope soon people will stop equating retro gaming with punishing difficulty, because they don't have to be that way!
Anyway, I'm looking forward to whatever you guys do next regardless.
