The Gravitation is not a map without criticism, but I think it's an excellent map in its atmosphere, and was carefully crafted in its item balance. However, there are places this map struggles to impress.

First of all, DO NOT play this map on Expert or Realism. It will be hell. I played it on Expert with a group of veteran players, and we had a blast. However, I would not recommend the same to anyone else; play on Normal for a blind run.

This map was clearly inspired by Buried Deep and does a good job of living up to that campaign. The environments are very neat and will take you to various areas that can provide a "wow" factor for the sheer scale and size of everything. However, due to the map being long as hell, they will drag on in some players' eyes. It took my group 100 minutes to beat this map, and we did not restart once.

The map gave plenty of supplies, ammo was spaced accordingly, and there were numerous grenades, but I do think there could be more Tier 2 weapons and medical supplies scattered about.

Amazingly, despite the size of the map, our group did not get lost once. There were some arrows to guide, and we occasionally took a wrong turn here or there, but in no area were we completely stumped. Chapter one is the best this map has to offer, and the holdout sections are excellent, feeling like an onslaught, but giving you the supplies needed to survive as well as not throwing a tank at you in the middle of it. Not to mention, the mounted guns are placed well, incredible!

The endings of Chapters 3 and 4 are the weak points; there are a lot of very dark areas that are impossible to see without the flashlight. Chapter 3 can get dull after the holdout, but it doesn't last long, and the finale throws 6 tanks at you (2 in first wave, 4 in second), which is not cool. I think this map was designed to house more than 4 players.

I think the map overall is good, but definitely not for everyone. Play at your own sanity, as this map is grueling, long, tough, but most importantly, fair.
