It depends on what you want. Marneus Calgar might be the one with the best abilities, along with an impressive statline. But he's too expensive. It really depends on the type of abilities you have.
Only certain ones, and you have to summon them. Look up how to in the chaos space marines codex. I believe they come in like reserves and you have to sacrifice an HQ.
You need to be more specific with which Space Marines you are referring to. Is it standard Ultramarines? Space Wolves, Black Templars, Blood Angels? This will change what upgrades they get. Then also, are you talking about tactical squads, assault marines, devastator squads, veterans HQ? It changes what you can add to each squad.
The best thing to do is buy the codex
space marines cool because they hot before now they cool.
It depends where you are in situation: Melee Space Wolves Range Space Marines Psychic Space Wolves (only just) Vs. Vehicles/Light Infantry Space Marines Vs. Heavy Infantry Space Wolves Look Unpainted Space Wolves Paint Scheme Look Space Marines All-Round Space Wolves (I Reckon)
NO, Valkries are for the Imperial guard. Space Marines use Thunderhawk Gunships.
Answer: It depends on how you use them. They are not to good at range, but when you get within 24 inches with a few boltguns they're amazing. Their tanks are pretty good but they don't have a substantial long range blast template weapon. Their fast attack is some of the best in my view, transports are really good for transports. Overall if you're looking for a short range good heavy support, and good close combat, Space Marines are your best bet.Another answer: In short no, the space marines are not the best. Each army has both its strengths and weaknesses. Space marines are powerful and one of the most popular armies, but they are small in numbers. Check out each army's strengths and weaknesses. Check them all out, find out which one YOU like best, if you like necrons go with them, tau go with them. Do what YOU want. In short again, space marines are not necessarily THE best.
No.
5 Marines = 90p. Each additional (up to a maximum of ten) costs 18p. + weapons.
It depends on the person who is playing, but Space Marines are considered to be the best all-rounders.
