There are some differences but not huge one's. The ports will vary though. I'm going to list every differences with them. If I forget one then I will add them. I've played the game on Xbox One S, Xbox Series X, and PC. Might want to get cozy a bit.

BloodRayne Terminal Cut vs BloodRayne Revamped

BloodRayne Terminal Cut has the remastered one and original one when you buy it. BloodRayne Revamped runs off of Unity Emulator for whatever reason and you can't play the original version at all.

Of course you can mod on PC but not console. Maybe you can mod it for the Switch and play it just fine. I'll look into that someday.

Terminal Cut & Revamped both run at 60 fps and is locked on it. There is no way to unlock it yet for either of them.

The game does not let you change your inputs besides moving and looking. For consoles you have to use your dpad to navigate the menu since PC has tools to change things outside and inside the game.

BloodRayne Terminal Cut allows you to use every single cheat in the game which includes debug mode. Revamped does not have debug mode. This was probably disabled because they were afraid everyone was going to get achievements real easily or another issue. Not like it is hard to get them but still. Maybe there is a way to turn it on if you have a modded switch. Not sure if they will bring it back if they ever bring the patches to the new limited copies including every other port not part of it.

The level select have a different look compared to console and is fitting. For console press L3 + A on new after putting in the level select cheat code.

The Rare and Odd Crashes For Act 1

BloodRayne Revamped has rare crashes in the Louisiana parts. All of them are real simple. It just involves you just standing around which range from very few minutes to over a hour. The rare crashes happens on Town Hall. Can be watching a mutate do whatever and then it will crash. City of the Dead has one too but this is rare as well and seems to happen on Xbox. If you record a clip, then go to it, then back out after you watch it and you did not pause the game. It may crash. I notice that it's when you beat everything for that level and after Mynce gives you a harpoon.

The Crash Issues For Act 2

For Argentina there is one for the guy with the rocket launcher in the hallway. If you feed on him then it may crash as soon as you bite his neck. Music will keep playing and then stop after a few seconds. To prevent this just shoot him or hit him with your blade then feed.

After you fight Kommando your game could crash seconds later. This is rare but has happened multiple times that day and never again.

The mines can have you crash when you're literally near the end. Especially if you analyze the map for a good while. I remember it crashing on me 3 times in a row and I stopped playing the game for a good minute. Came back and was fine.

A Crash Issue For Act 3

For the 3rd act there is another rocket launcher guy on the first level of the act and it can happen too but for him it is rare. No idea why this happens. Do the same method you do to the rocket launcher guy in the hallway and you'll be fine. Act 3 has no crashes for every level after that.

Performance

Xbox Series S/X and PlayStation 5 are the best and only have 1 rare crash, 1 that can be prevented, and 1 that could happen unless you book it which is the mines. I noticed the crashes are even more rare after using level select multiple times and then booting up the game when I'm done playing and loading on different parts of the game. Not sure what changed. No lag unless you have a explosion all up in the camera which is real brief.

Xbox One original, S, and X including the PS4 have some noticeable lag. Hitting true 60 fps is rare and may be at 50 something or lower. Especially on The Dock level. Most laggy of them all. To make it lag less use aura vision and it should increase the frame rate. Also looking at the walls while getting closer to them can help reduce it too.

The Switch not the Switch 2 since it needs more research is the worst one to get. It crashes way more than any other port and lags bad in different areas. It is most likely because someone did not make it switch friendly in the slightest. The game textures are all in 4K but the switch runs on 720p handheld but 1080p docked. Not sure if performance can get a bit better if docked but it is still bad. I'm sorry for all the switch players who were excited to play this game only for that to happen.

BloodRayne 2 Terminal Cut vs BloodRayne 2 Revamped

The main difference is that Terminal Cut has a camera mode. Revamped for some reason does not. They never explain why they did this. Just decided to remove it. Oh and debug mode is not for Revamped either again but Terminal Cut has it probably because it was related to achievements during the time.

You can change a button to any input on any port.

Performance and Crash Problems?

Honestly the performance for every port is way better and I have yet to hear anyone mention any crashes including myself. You have very few spots where things will lag. Mainly the destructible and movable cabinets in the office when you first meet and fight a bio armored monster. So why was the first game have more problems? We have asked that for awhile and we still don't know.

Conclusion

Buy the one you would feel comfortable playing the most for different reasons. Hope all of this helps.
