I skipped Reach so, I'm coming from a perspective not as devoted to map control and player balance. I enjoy the multiplayer for the most part. I'm lvl 75 now and unlocked Pathfinder and Pioneer. Going for the weekly challenges for the bonus xp has kept the journey interesting. It forced me to play more small maps with modes I don't prefer, but that gave me a better feel for what weapons and armor abilities you want to use where.Guys, back in the days I loved playing Halo: Combat Evolved either with LAN or online multiplayer on the Xbox. I bought Halo 2 and weren't the biggest fan and then skipped Halo 3, Halo: Wars, Halo 3: ODST and now Halo 4. I bought the novels but I couldn't get myself into the universe or story-telling.
I haven't subscribed to Xbox Live for years but I got 2 weeks free Gold subscription with my Tomb Raider copy and would like to try out a great online game, preferably a shooter - also, I absolutely love MAG on PlayStation 3.
I see the 2 huge ones on Xbox 360 are Halo 4 and Call of Duty: Black Ops 2 but they both seem to be very competitive with a lot of little details, perks, upgrades, customisations and what not.
Is Halo 4 worth getting for online multiplayer?
Anyway, since I didn't play as much in the past versions, I don't have a problem with things like the new weapons, people sniping with cloak, being able to EMP vehicles, or one shot people with the Boltshot. It has made the game less chess and more poker and I guess it would have been nice for the devoted players to keep chess modes. In any case, I think you should play the game to decide for yourself. I mean they relented and returned the scope to the magnum and took out dual wielding to return more to the original trinity mechanics. Also, the one hit OP wpns also have weaknesses that can be exploited. Like the BR lays out an orange beam that gives away your position and the Incineration Cannon has an uncomfortable cooldown after one shot. Unskilled players cannot take full advantage of them. Really, one of my favorite moments in all of multiplayer gaming was getting a good gausshog driver and rolling up 30 kills on Exile. Edit: I've also had the good, but less fun fortune of being that driver 2 or 3 times that facilitated someone getting 20-25 kills.
All that said, if you loved MAG (more than Halo CE), BF3 might be more to your liking.
