As I said before,
Warhawk Operation: Fallen Star brings with it a new map and a new vehicle to use. "Tau Crater" is a small symmetrical map, but more about the vertical space since you can perch upon the giant Chernovan ship that crashed in the middle of the map. The real reason to buy the add-on is for the "Icarus Mk. 1" jetpack. They handle just like a Warhawk, but less nimbly. The jetpacks are available in all of the previous maps and for all game modes, which changes the playing field drastically.
"Capture the Flag" was always tricky on the bigger maps because it was very rare that the host enabled the flag runner to fly a Warhawk. Now with the jetpacks, the flag runner can fly over, pick up the flag, hop in a jeep or tank and take off with little detection. The best part is that if the vehicle comes under heavy fire, just boost out far enough away to find another vehicle or reinforcements. Another useful strategy is to just hover underneath a bridge with a rocket launcher and wait until the right time, but be careful. Since you are mobile, you can be locked onto by enemy rockets as well.
Warhawk Operation: Fallen Star was released just a few weeks after all of the free summer updates that included two new game modes and trophies. The new map is really fun when playing "Hero Mode," which is just like "Juggernaut" in Halo, but with teams. Each team has a hero that has access to all of the weapons and increased health, but the catch is that they have a time limit on how long they can be the hero. The other mode is called "Collection" which functions like multiple CTF. There are many points on the map where tokens appear and the point is to collect as many tokens as you can and bring them back to the base. You can carry up to three tokens and you can pilot any vehicle while carrying them. The last part of the update was the long awaited Trophies. There are 57 trophies in all and 12 of them are tied to each add-on at four trophies each. Some of them are retroactive, most are not. They do a good job with variety making some of the trophies fun, and sometimes humorous, to earn. There is only one platinum trophy for getting ALL of the other trophies which means getting it isn't going to be easy.
