Additionally bullets to any place on the enemy AI's upper torso at low to medium range with an M4 or something similar kills with a single hit on Regular difficulty-unlike the original where only headshots resulted in one-shot kills. However, I have a sneaking feeling that the enemies don't infinitely spawn anymore when you camp in one spot (like I think the original did). It may be down to the fact that I was playing a couple of levels on the original and then jumping to the remaster to complete the same levels. Gameplaywise things are more or less the same, but the game felt a lot easier to finish (5 hours vs the original's 6.5 hours). Now this isn't a mil-sim and the weapons don't sound like ARMA but everything feels a bit more grounded, which I feel adds more weight to each bullet. Other major overhauls I noticed are the UI (which looks good) and sound, especially the weapon sounds which get rid of the original's booming Hollywoodish sound effects and replace them with something more 'realistic' gunfire sounds.

The visual overhaul is really nice, all the models have higher detail, the lighting is a major step up, the textures look really slick and modern and the color palate has been slightly tweaked to make everything appear more 'realistic.' Having said that, this a game from 2017, so its more than five years old and it predates the big visual overhaul CoD games had with the launch of the rebooted Modern Warfare series. Most of the changes I believe are visual with the original's gameplay largely remaining intact.

There are a few obvious differences though. I played this game almost side by side with the original (which I was replaying for the first time in nearly 15 years) and the things I said in my review of the original game mostly hold up here as well.
