I'm enjoying it. The gun play is pretty tight and you can actually take more than 3 shots without croaking. The unlocks look pretty cool and I like how the powerups are all over the place (including the ships). The heroes you can become seem a bit OP but maybe I just don't understand how best to defeat them yet (they are heroes, though). Graphics are great, as is the score.
I also like the map design. It feels more like a classic arena map (on a huge scale) where you actually have space to move in and out of without being shotgunned every step (like Destiny) or killed in one burst (like CoD). There are paths and while rushing is not recommended, it is also not insta-death like all other games now-a-days. The game reminds me of Bad Company 2 a bit (which is great).
As for the weapons, it's too early and I haven't played with them enough. The sniper I have is cool, but only 1 shot every 20 seconds or so, something like that. There are other weapons like that but I haven't unlocked them in MP. Pistol are great for upclose dps, blasters come in all types. The perks are going to be fun to mix and match. Inviting a pal to play and splitting perks to compliment one another (and the objective) looks to make things more fun (and survivable).
The Missions seems like horde-mode but are a nice way to get sort of easy offline XP. I think the split screen co-op will be nice on those. I wish they had online matchmaking...maybe they do but all I can see is to invite a friend to them. I've only done the command point and team DM mp modes so much more to explore.
I need a break from Destiny, and I think this is the one that will fill the void until new Destiny content/raid is released. FO4 for when I want to just explore, CoD single player for some popcorn action.
It's a good Q4 for gaming, and there will be plenty to do over the holidays.
