I had an epic win streak on free for all last night, I won about 9-10 games in a row played to 6 in the morning because I kept winning, yes free for all.
My impressionsand criticisms.
1. The gameplay and maps are solid, very enjoyable, only caveat is I wish they designed it it to limit camping areas ie. the back of the warehouses with the wooden crates in the missle silo board. I never understood the criticism from dying in a couple of shot's, it's not halo you're not master chief and you dont have a suit of armor, with shields.
2. Shooting someone and watching the guy jump to try to dodge is worth the price of the game alone. Halo much.
3. Matchmaking is broken, it's not too noob friendly and may put off a lot of people. Currently I'm a 24 and even at lower levels I was matched with levels 40-50, and 4-8 on the same game.
4. I think the martyrdom perk is too powerful. I use it too, because it is that good. I would recommend patching it so when when you get a headshot, or you knife the opponent from the back stealthily the perk does not activate.
5. p2p play is somewhat bad. I got killed so many times where I would shoot them them first and die. In the replay it shows I didn't first, or I was shooting to the side of him. Once I was blasting a guy from the side in fairly close range for about 2 seconds he turns shoot me once and I die. Same applies to knifing
6. Claymore's kicks ass nothing more satisfying than planting one in the entry point to the room you're in and getting the +5 on you're screen for the kill, while you're looking out the other side of the room looking for victims.
That's about it for now having a blast playing.
