Genuine waste of time made by people who really didnt understand the source material.

The good

• visuals are great although typically unreal engine 5 issues abound its largely a modernised recreation
• guns feel and sound good but are mechanically broken

The bad is everything else

• the music in 343 guilty spark is muted so theres just no music at all for the whole level
• the bonus missions give you no guns and some of the worst arenas ever put into a game, no cover, no ammo, no counter to the aimbot enemy spam
• one hit kill sometimes phantom bullet jackals. The number of instant deaths ive had on only heroic is wild
• cant shoot jackals hands cos aim assist and bullet magnetism is broken
• hunters just cant be dealt with they rapid fire and always face you i ended up having to shoot their feet
• one hit kill melee most times also theres no sound or animation so you just die. Also enemies just really like rushing you now for the one hit kill invisible slap
• difficulty balancing doesnt make any sense
• every cutscene is redone to be worse for reasons unknown
• all the voice acting is worse and lines cut for no reason
• no multiplayer
• spawns enemies behind you for reasons unknown
• enemy spam enemy spam enemy spam holy shit what do you mean i walk into a room with 10 elites half of them invisible with nothing but retreating back where i came from as an option?
• the library for all its ills in the original is just devoid of life in this one
• 10 minute tutorial for the final mission to blow up the engine like ok cortana we all somehow managed when we were kids
• “the ship is going to blow up in 5 minutes, when the 5 minutes is up the ship will explode, we need to leave before the 5 minutes is over”…. Ok
• not a single fucking wort wort wort
• visual readability is atrocious the number of times i just didnt see an elite walk past me was unreal
• cant hear low shield noise
• cant see low shields
• ai is either bugged out staring at a wall or headshotting
• warthog physics are bugged
• vehicles have like 2hp and can survive 3 shots from a single grunt before exploding and have no telegraph so you just die
• hunter spam around every other corner
• flood hunters come in packs of three for some fucking reason and can eat all your grenades and ammo
• plasma rifle is useless now
• human weapons generally feel much stronger and covenant weapons much weaker
• waypoints EVERYWHERE
• you cant see any weapons on the floor, half of them despawn i imagine cos ue5 cant handle it. They tried to add little markers so you can see them but you basically have to be on top of the weapon for them to maybe appear
• enemies disappearing the instant they die just popping out of existence
• the bonus missions are also terribly written and the needle rifle is basically mandatory cos nothing else does any damage. Its also walk 2 feet, circle arena with no cover, walk 2 feet, circle arena over and over
• youve heard of sniper jackals? What about sniper elites!
• phantom homing grenades that one hit
• sticking someone with a plasma grenade may as well be tickling them. They also rush you when stuck so you die and they dont
• checkpoints are busted i once got stuck in a death loop of getting exploded by a rocket grunt 1 frame into reloading until rng deemed i could live after the 8th death
• overshield gives you 1 extra bar for reasons unknown to anybody
• invis doesnt work you can still be seen and enemies will still run towards you even if they wont be shooting at you
• oh yeah and they added sniper jackals into the game cos why not

Theres probably more but i didnt take notes. Its like that meme where “if Ubisoft made elden ring” idk how it has any positive reception at all other than halo fans being desperate (which is me which is why i wasted my time playing it)
