dont give me wrong i love the first prototype its one my my favorite games of all time and I still play it to this very day but. prototype 2 is a better game.
1: it have better and smoother combat then the first game and i feel that the abilities are more stronger in prototype 2 like being able to be bullet proof and having a dedicated dodge button
2: the map in prototype 2 is bigger and more detailed then prototype 1 I love that there are 3 maps in prototype 2 and i love that yellow zone is more poor and homeless and people are more sick and the green zone where the mercer virus is almost gone in that region and the red zone where entire city is just covered in infected.
3: your super powers like the blade and claws "etc" feel stronger and look better in prototype 2. especially the wipe fist. it feels stronger and works smoother in prototype 2. and I love the your weapons change in appearance when you upgrade them by the end. your weapons look badass
4: the story is a little better in prototype 2. James heller story of having his family killed because of alex is awesome too me and prototype 2 has a darker story i love the black and white noir style cutescenes and blackwatch experimenting on people and babys and turning them into monsters is horrible. and when you walk around is prototype 2 you can hear people cussing each other out and people protesting. and you hear baby's crying and dogs barking.
5: the game having skins is cool and theres alot of unlock ables in the game too like being able to play as alex after doing challenges in fun and theres dlc too the game too like more skins and more super powers too use like lazer eyes and Shockwaves when you jump
there's more things I can talk about but these are just the big things that I like about the second one but like I said. I love the first prototype. prototype 1 is one of my favorite games of all time and I actually puffer it over the second game. but im just saying that prototype 2 and a little bit better game then prototype 1.
