Yes, It has 8 nacelles total, 4 on each side, two sets of two with a unique full size warp core in each nacelle housing. The ship can fly at warp with the armor plates closed or open, but open is much faster and efficient.
The Infinity, for all purposes is essentially a flying battlestation, and can actually deploy as a full fixed battlestation when needed. A few other noteworthy things about the ship....
This vessel is designed to ram other vessels, and uses a soliton shockwave generator, as well as sending the ship into a corkscrew spin to create a "comet" like mode that can crash through and destroy even the largest ships.
The armor is a Molybdenum/Neutronium composite, with retractable pure Neutronium plates. When the armor is fully deployed warp travel is impossible, but the ship is almost completely invulnerable to energy based weaponry. Weaponry is very limited when armor is fully deployed.
The entire hull is essentially one large charged phaser emitter, allowing directed phaser fire from almost any point on the hull.
The vessels transporters are so powerful she is capable of beaming up to 5000 individuals at once.
She carries 58322 Starfleet Marines in full barracks on board.
The ships main core is powered by the only stable omega particle in existence. Everything but impulse and warp travel is powered by this "Omega Core".
The vessel's Neutronium hull and lattice structure interferes with communication and beaming. Beaming has to be done site to site on board, and communication is by wire only.
The only vessel in service that has a complete set of manual controls for almost every system on board.
This ship has a complete holographic projector system on board, allowing any and all holographic projections to be projected at any location on the ship, central to the ships internal defenses.
This vessel has the largest hangar bay of any Starfleet vessel ever constructed. The bay takes up almost a quarter of the ship, and is large enough to fully house an Excelsior class vessel in drydock.
She has a Quantum Slipstream Drive installed, but safe use requires channeling the field through a warp nacelle instead of the deflector, destroying the coils in the nacelle. This means the ship can only "jump" 8 times before it can no longer travel at warp, as all warp nacelles are destroyed.
The ship uses a non standard deck layout...the bridge is deep within the ship. Most critical stations are deep inside the core of the vessel.
The vessel has the equivilent of 250 phaser banks, with type Z output, each capable of generating 10 times the normal output of a Type X emitter in overload status. That basically means that the phaser capability alone is equal to about the total phaser output of approximately 30 Galaxy class starships.
The ship has 34 torpedo launchers (14 fixed and 20 rotary), and carries 3570 photon torpedoes, 1680 quantum torpedoes, and 20 tri-cobalt phase torpedoes. She also has 20 drone launchers with a compliment of 170 offensive drones.
As of the the "Whence come I and whither go I?" story arc, the main computer on board (called "control") is sentient.
The ship has 5 Borg crew members, two head doctors (one holographic), an XO that was created from a transporter accident (Thomas Riker), a Klingon First Officer (Kurn), an android security officer that was once an enemy of the Federation (Lore) and a Captain that is the Commander of the Starfleet Marine Corps...as well as being a Eugenics product and brother to Kahn...General Raven Noonien Singh.
During the "Et tu, Brute?" storyarc it is established by Starfleet Intelligence that the Infinity class has firepower equal to roughly one quarter of Starfleet.
Just a few tidbits....
On a final note, I couldn't make the ship this powerful and put it in the game. It would basically be a god ship. It will be powerful, about in line with other Capital Dreadnoughts.
