I did not intend any Heresy. Of course the DW Knight is the epitome of his emperors warriors. From a TT perspective though, it is equipment, that sets them apart. Well, that and the 'shield wall, smite, etc'! I think I just talked myself into your perspective. Hero for the DA they are.
Terminators should be available to free players who spend Req points earned by playing as well as purchasable with cashmoney dollars. This means they still provide income for the dev, but any hardcore player can earn them in a month or so of playing. Terminators should have Vehicle Armor (invulnerable to bolters), but be super vulnerable to Power Weapons, Krak grenades, and Las Cannons. This means each Terminator player feels like a mini tank (they should), but can be easily countered by any team that uses anti-tank weaponry. They also shouldn't be able to crouch or use cover, the armor is intentionally restrictive. I also want at least one load out option with a teleporter, this makes pushing with a terminator more viable, since you can rotate out as soon as they take heavy damage. DW Knight and Grey Knight loadouts for the SM Terminators would be a dream come true. The weapon/shield and psylance/psycannon loadouts could simply be balanced with the default weaponry (this is not true to lore, but it would make for fun, balanced gameplay). Obliterators and Possessed Marines for Chaos would balance this out, possibly with a damage bonus for Daemon-hosts against Grey Knights and vice-versa. My mind is exploding with ideas, I'm very excited to see how Terminators are implemented!
It makes perfect sense since we're fighting the Deathwing and Abaddon the Despoilers leading the Crusade. There are probably lots of Terminators around.
You do know Grey Knight fluff has gotten way better right? I haven't heard about Kaldor Draigo in months except that Slaanesh may of devoured his soul if he's the silver armored warrior in the Daemons codex, Ward also left quite some time ago.
Terminator equivalents are planned to be included in the first free expansion planned to be 1-3 months after launch (announced near the end of State of the Crusade IV here + thread about free expansions & $ content, termies included, here). As a gameplay element everyone with the full game has access to the standard versions and these are accompanied by Rogue Trader Store stuff, such as cosmetic variants (if something in the RTS has stats they will be obtainable by in-game methods; see question 10 here). An in-game currency known as Badges is taking over handling players spawning as Elites & Heroes instead of Requisition Points (RP), which Terminator equivalents will be - see questions 7 & 9 here. ---- There's a Grey Knight ideas thread here if you're interested.
I wouldn't say invincible to bolters Given enough DAKKA you could kill anything But they should definitely have high resistances to such weapons
I feel like a bolter round should do ~1/10000th's of a tanks health. It's not invincible - but if a tank is limping along already - flaming and broken - and surrounded by Boyz firing at it - at some point it has to pop.
I hope we see something like the Space Hulk terminators from the more recent Space Hulk, these Blood Angel ones look damn good. Also a Blood Angel's, Death Company Terminator picture [Chapter master Caedis].
I would imagine them looking less detailed on the onset, but with a lot of additional details available later on.
