OK, perhaps I was a little premature in my initial impressions review...
I maxed out to level 8 on the Hunter class, having reached level 4 this morning with Titan, I'm enjoying myself more now. Here are my updated impressions:
+ The Halo holy trinity of melee/grenade/primary is still fantasic, the core gun play is enjoyable
+ Graphics are fabulous, though 60fps would have been nice, I do appreciate the graphical fidelity, especially the shadows which are amazing
~ Fusion rifle and hand cannon... erm, tis all about the shotgun and auto/pulse for me. I hope the weapons become more diverse in their own class as you level beyond 8!
- Still have concerns the game may become repetitive, though I stand to be corrected once the world opens up as does the multiplayer game types
- Still not liking the no respawn thing when tackling big bosses, as it's wholly dependant on your public coop team mates being strategic or just damn idiots. Though nod to the fact that playing with friends would be wholly different, shame I don't have any
- To me, still doesnt feel like theres a lot of loot like Borderlands, the world seems a little empty really. I still dont understand the mechanics of how I bag new weapons and equipment, is the system entirely random? Stuff just seems to appear from weak enemies as much as it does from bosses. The odd crates I find just seem to have the blue gemstone things in - no weapons or anything?
FYI - for anyone like me who was disappointed a little, try another class before you give in, the Titan class is much more my style and I really like the grenade, jump and special on this class, plus the additional armour lets you have a tad more fun.
