The maps are small and have a very Halo 2 and Halo 3 feel to it which is very good.
The first map I played was Landfall Infinity Slayer which Landfall felt like Longshore from Halo 3 mythic map pack it had a very straightforward approach to the map which made the map easy to find people but with different levels.
The second map was Monolith which had a very Halo 4 feel in terms of how it looked but had a new feel which I think its the best map in the entire pack I played some king of the hill the grav lifts had me and others jetpacking off them trying to get to hills it was a blast!!
The final map was Skyline which felts like a few Halo 2 maps since it was like a city. I played the new gametype Infinity Rumble on it which was quite fun and the map had about 4 different levels so it made it fun to drop on people and kill them.
The map is better than Crimson and is about a top 5 Halo map pack off all time gives everything you could ask for new modes, new maps, new fun.
