I really, really appreciate games where higher difficulty does not arbitrarily make enemies harder to kill by giving them super-armor and lakes of health, or turn you weapons into airsoft garbage. Alas, this is pretty much all modern gaming can manage, as advanced scripting for enemy behaviors doesn't sell well to stockholders. FEAR had pretty amazing scripting by all accounts, so it would be nice if more could be done, what with the better technology, more RAM, and more storage space available now.
Shit difficulty:
>Enemies have double HP
>Enemies take half damage
>Enemies are immune to stun effects
>Enemies' attacks deal double damage
Boringlands, Too, and the DLC-quel take this to the extreme, where enemies can have literally billions (if not trillions) of health points, and even if you have an insane combination of passive skills, "badass" rank bonuses, and all legendary or better equipment, you'll still be two-shotted by anything. Your best scoped rifle, with everything you have equipped geared to doing the most damage per single shot, will not allow you to one-shot tougher grunt enemies at high difficulty. Meanwhile, a new character on normal difficulty with basic, common equipment, can one-shot damn near every enemy up until the first boss, and most afterwards until late in the campaign. Most of the patches for these games were made with the singular purpose of breaking the synergies of certain equipment and skills. For instance, in Boringlands, Too:
>legendary shotgun called the Conference Call
>when fired, two identical blasts are fired toward your target from the left and right, so each shot is basically three shots
>there are shields that amplify the damage of your shots, but this amplification takes a few seconds to recharge with each use
>the amplification effect would apply +X damage to each projectile you fired, at once, making shotguns that fired many pellets simultaneously, very powerful
>the legendary amplification shield, The Bee (as in, sting like one), had no delay on the amplification
>every single projectile you fired, while your shield was full, would be amplified by a large amount
>conference call could fire 15 or more pellets with each shot
>The Bee amped each pellet by a large amount
>you could liquefy the raid boss in seconds
<patch comes out to only allow amp damage to add +X damage per mouse click, dividing the amp damage across all of the pellets in a single shotgun blast, instead of multiplying it
They did this kind of shit all of the time. Shit game captained by a massive cuckold sex pest and an embezzling cheese pizza enthusiast.
