Mkay, so, I got a copy of this game's bata a couple days ago.
I don't like it.
If you like CoD, you might love it, but for me there are too many realistic or tedious things about it.
For example, at the beginning of a match, you pick out your special ability. You can have a rocket pack, temporary invincibility, a run mode, or things like that.
The graphics are really nice and I love how the needler looks, but um, yeah, I don't like realistic shooters.
Ok it's not that realistic, but it's a mix of CoD and Halo 2.
One thing that I do like though is that you can vote for which game type and map you play. Plus, you can change your vote.
It's not too different, but it is. Either way it'd take getting used to; much more so than ODST.
But yeah. Things like your ears ringing after you have a grenade going off near you or your sound fading when you are invisible, or much anything really, have made Halo too life-like for me. When I'm playing a shooter game I don't want to feel like it's combat related or violent; I just like to t-bag and get a few laughs.
I suppose it's not that hard or anything, but it's definitely a game you'd have to be in the mood for rather than one you can just relax and play.
Edit:
I like it a tad bit more now that I'm used to it, but eh...
Halo Reach's Beta is now available to anyone with ODST. That means that I get to kick ass now because I know where all the power weapons spawn XD
