As a long time fan of the Halo series, I have enjoyed every Halo game to some extent, and I am sure that if I buy Halo 4 I will enjoy that to some extent too, however, After reading all of the details that have been released, I am seriously considering not buying the game because I am simply not happy with almost all of the changes.
Spartan Points -
As long as the amount of points you have doesn't contribute to you rank like cR do, I don't care
Spartan Ops -
*sniffs* Hmm, I smell fish here, specifically CoD. But OK, a "new" gametype cant hurt, can it?
Why Reds fight Blues -
Do we really need a reason? And this reason isn't at all Cliché.
Sprint -
OK, sure, but couldn't they of just increased the movement speed?
Forerunner Vision -
lolwut? See through walls? Seriously?
Returning Armor Abilities -
Jetpack - Ruins map verticality
Hologram - Useless
Invisibility - Better as a map pickup
Elites not in Multiplayer -
Sure, OK, I have never really cared about the Elites, but the Elite "community" must be really pissed off at 343.
Loadouts -
Being able to chose primary, secondary, grenade, armour ability and perk to start the game with? No thanks, WTF is 343 doing?
Grenades -
4 types of grenades? Sure
Returning and new weapons -
Battle Rifle (Yeah, cool)
DMR (Uh, dont they fit the same weapon role?)
Covie Carbine (^^^^^^)
Assault RIfle (Of course)
Plasma Pistol (Yeah, sure)
Sniper Rifle (Of course)
Shotgun (^^^)
Rocket Launcher (^^^)
Energy Sword (^^^)
Assault Carbine (Sounds like an Assault Rifle/SMG hybrid)
Firefight -
Far from perfect, but do they really have the need to remove it?
Regicide -
New game mode? Sure
Distraction and revenge medals -
So rewarding people for sucking? lolwut?
Random weapon spawn -
What? That doesn't make sense? Whats wrong with dedicated spawn locations?
No more respawn delay -
So its not punishing people for dying? Death = Teleport
Joining mid-game -
Long overdue, but it could potentially screw up the ranking system (If its like H3/H2)
TL;DR
Captcha - Oh Yes (How fitting)
