Few thoughts on the DLC:
1: As Biron said, Ignition is pretty much a remake of Scrapyard. I don't know if that's been common knowledge from the word go but after running around the map for about 5 minutes I noticed.
2: Fog is my favourite map, just non-stop action very chaotic. As whacky as the idea of having a Michael Myers killstreak is, I actually enjoyed it. I like Bayview and Ignition as well.
3: Containment, I like the map but did anyone else experience lag and framerate issues on this one last night? It seems everytime this map came on it was like a powerpoint slideshow especially near the middle of the map on the bridge, I doubt it was just me either cause I noticed a lot of people leaving during games on this map. This is on XB1.
4: Maverick AR, I struggled with it at first and I hate putting grips on guns but it's an absolute laser once you have the grip on it. I feel it gets out of my control a bit even at medium ranges without the grip, just running grip/silencer on it for about 2 hours last night and I was tearing through people.
5: Didn't play on the old maps last night so can't comment on their spawns but the spawns on the new maps aren't great, I don't mind it happening on Fog because that's just the nature of the map there's action happening all over it but on Bayview and Containment I got tagged as I spawned quite a few times.
Overall, had a lot of fun. Can't wait to get online again later.
