Are you new to the Halo franchise and do you want to try it? I would highly recommend getting Halo: The Master Chief collection instead, since it more or less contains this game, and the rest of the franchise (2, 3 and ODST are the best IMO), more multiplayer modes than just campaign co-op and is often found for the low low price of 10 euros. But to anyone else who wants to play Halo CE (the old one) with new graphics and a expanded sandbox I can recommend the remake, though it wouldn't hurt to wait for a sale.
Halo CaE (Campaign Evolved) brings halo to unreal engine 5, which is a good stepping stone for more easily creating new gamesin the franchise. It plays mostly the same as Halo CE did, but changes some things up with additions from later titles and mixes up some of the leverls a bit, often for the better.
"New additions" contain later weapons such as the Fuel rod gun, Energy sword (both technically existed in 1 but were not useable in campaign, [Fuel rod existed in multiplayer on pc]), an assault rifle that actually does damage on legendary, a plasma pistol that actually disables vehicles on charge shot, ,battle & needle rifles,sentinel beam and more. The vehicle Jack system introduced in 2 finally is addes allowing you to highjack enemy vehicles when getting up close, and some enemies from later games such as suicide grunts, pure form tanks and everyones favorite on legendary: Jackal Snipers. Overall it makes the campaign feel more fresh (I myself have often missed some mechanics from halo 2 and 3 every time I played CE, though I wish they included dual wielding) especially when combined with map changes.
There are plenty of small map changes, most for the better (though some out of bounds killboxes are strict). Minor things such as the "Not a natural formation" tunnel getting slighly changed, the truth and reconsilliation containing less hallway and more functional rooms when gettings towards the prison, several changes to assault on the control room making the inner rooms feeling a lot less like the same room over and over; [spoiler]But the biggest and best changes are in the flood levels. The use of flood growth to both change the look of the levels you pass trough a second time, and using flood mass to create walls and such to slightly change the layout of the level both look and feel a lot better. The maw got a lot less rediculous replacing a weird mid section bridge in a spaceship with far more sensible damage to explain the open areas; and everyone's favorite level, the library got a complete overhaul. And the looks and atmosphere in 343 guilty spark is just perfection[/spoiler]
Then there are the new cinematics which are amazing, often giving a far more complete overview of all the things going on in each of them than what the original ones did. They are no longer rendered in engine, but like in halo 2 aniversary they look a lot better and far more lively.
There are 3 new prequel bonus missions, which are OK. I don't get the hate for Williams much, seeing she's just another ODST for the most part (and yes female ODST's existed in prior games: Veronica Dare). They are decent enough missions, nothing fantastic but a lot more fun than most missions in Halo 4 for example.
Some voice actors have been replaced, most notable Johnsons and Keyes. I do not know why Keyes got replaced but Johnson's VA is retired, and the new VA does do a good job, but did require some getting used too at first.. Keyes's new VA has less presence but also felt ok enough. It takes some time to get over the nostalgia of the voices I've known these characters to have had for 25 years and judge the new VA's in a void, but in this uphill fight trying to at least match the amazing work of the old VA's I'd say they managed to get pretty far up the hill.
There are definitely some things I am less enthusiastic about. First and foremost is the increased handholding. Especially when playing on legendary, cortana (and chief in the bonus missions) stating some obvious things that any player easily managed to figure out. Pointing out stealth elites with markers is kinda stupid and [spoiler]Having navpoints in 343 guilty spark removes the extra fear produced by difficult navigation in dire circumstances[/spoiler]. I would recommend turning markers off for the best experience.
Then there are some changes in audio I dislike, the Magnum and Sniper rifle really were more fun when they were louder, and better conveyed how much power there was in these weapons.
The choice to use Halo Reach's elites is ok-ish in my opinion. I would much rather have elites more resembling those in the original trilogy, but at least they did not use the halo 4 or 5 models.
Also the cosmetic dlc for this game (a singleplayer/co-op game) just feels stupid (and would probably have been a progression reward if this was like halo 3), especially when for it's price you can but the MCC.
The remix option is great as far as I've tried it. It could be even greater if there was more choice in which enemies (or even allies) with which units, and which weapons with which other weapons, and perhaps save and share these presets. All without the "All enemies work together" skull.
Overall I do like Halo CaE, and it gives me good hopes for a Halo 2 and halo 3 Remake (hopefully bundled, with the H2A cinematics for 2 and modes like firefight, or perhaps some bonus missions more focused on the sanghelli).
