YMMV / Warhammer 40,000: Chaos Gate - Daemonhunters

• Awesome Music: The Ultramarines Chant - Remastered, except the chant doesn't include mentions of the Ultramarines for obvious reasons.
• Demonic Spiders.
  • Plague marines with melta guns are way above other units of their rank in how much danger they pose to you. Their melta guns not only hit hard, they inflict Armor Break on your units, permanently reducing defences of whatever they manage to hit - with an extra strong version of said attack if they manage to get close to you and fire point blank. That one can potentially oneshot a knight, especially if he's already wounded. In addition to that, they can throw grenades - that not only inflict Armor Break as well, but destroy cover. And the worst of all, you cannot disable that attack - even if you destroy their ranged weapon hand with precision targeting (which effectively neuters the threat with bolter or toxin spewer plague marines) they still retain their grenade throwing capabilities. If with other basic plague marines you can afford to be aggressive and quickly overwhelm them, marines with meltaguns require very precise and careful handling, otherwise they can cripple you for the rest of the mission.
  • Nurgle Blightbringers. They are completely immune to any and all psychic powers, preventing you from using most of your tools that help eliminating threats faster against them, not even the basic Force Strike or Psy Bolts, which in most cases leaves you with nothing but bluntly pouring basic attacks on them until they go down. Which is a problem, because they are spongy and they have a strong area-of-effect attack that not only hits hard but inflicts Silenced status on your knights, preventing them from using psychic abilities until it wears off. Considering how much of your effeciency rides on your psychic abilities this immensely hamstrings your knights, and potentially leaves the whole squad dead in the water.
  • Lords of Virulence. Even stronger plague terminators, they are tough if straightforward opponents but what makes them really dangerous is that they give all active units on the map Armor Piercing for their attacks from just their presence alone. Your 10+ armour points on your terminators now mean nothing.
• Fridge Horror: Gameplay challenges aside, your Knights are fully capable of dealing with their enemies, but what about regular humans? Missions where you have to protect sanctified servitors alongside some imperial guardsmen offer you a glimpse of what it would be like for a normal man to fight what you have to fight, and frankly, it's horrifying. Without your support guardsmen tend to be quickly swarmed and overwhelmed even by regular cultists, and stronger enemies like daemons or - God-Emperor forbid - plague terminators are so beyond them they might as well be throwing spitballs at them. They get showered with grenades, drowned in toxins and plagues, blasted by Chaos sorceries, gutted by rotten diseased blades and swarmed by pox-ridden reanimated bodies of their dead comrades, and all they can put forth to oppose that are their pitiful lasguns and way too thin armour and battlements. Guardsmen tend to get inflicted with a Panic status every time they are attacked, and with those odds, who can blame them?
• Goddamn Bats: Cultist Grenadiers. On their own they are actually unable to kill your knights unless you allow them to, but they're great at hampering them and flushing them out of cover.
• Underused Game Mechanic: The Venerable Dreadnought. Unlike the Techmarine from the same expansion and his combat Servitors, or the sanctioned assassins from Execution Force, who can be used anywhere the player so chooses, the Dreadnought's presence in the campaign is entirely limited to the Duty Eternal story missions and specific Technophage Plague outbreaks, which are few and far between by comparison, and even worse still if one of those popped up while he's still under repairs following a previous sortie. In fact, the Duty Eternal DLC got review bombed to the ground because of how little involvement the Dreadnought has in the game at large compared to the pre-release hype, since the majority of players bought the expansion specifically for him.
