I probably got 4 good hours into the Beta today. The general impression is
really good. This is Halo, yet definitely different. The best part really has to be that I don't think I have played a 4v4 game with so much action. But it isn't "Oh, great, I spawned with 10 people around me" action. How the spawns are setup, map layout and objectives, weapon range, radar, etc you can always find action. With the sprint, active camo, and jet pack you can always get into it quickly. Because you can spawn with a friend you can more easily work as a team as well. Kudos Bungie.
The armor abilities really breath new life into old standbys. e.g. I have the most intense, and fun, game of Team Crazy Hill in may years. The last King of the Hill I really thought was great was MW1 Headquarters; this may be more fun. It is very fast paced and with Camo, Jet Packs, and Sprint there are so many ways to infiltrate and hold a hill. It is a blast to fly over, drop a couple nades and then descend down--or even use this as a defensive tactic by flying around and over the incoming enemies and flanking from the rear.
SWAT is a blast but I won't try to explain why in fear of Scott killing me
3 Pole (Territories) was also a ton of fun. I love BF and always thought Halo missed the boat on offering a Conquest/Territories style game that was refined. Territories was horribly unpopular in Halo 3 because it was the same old: everyone rush to a zone, throw nades, and hope you get there last to take the territory. In 3 Pole in Reach it is first to 300 points and you really just need to hold 2 flags. The ability to sprint, fly, and disappear really add new strategies. The map (Powerstation?) has a lot of catwalks and cubby holes with great evelation grading downward so there is a lot of strategy and map control involved--making a beeline on foot while tossing nades is a good way to let the more tactical players get easy kills.
Stock pile is ok once you figure out the maps but the objective markers need to be redone to be more visible and usable. I am sure I will get used to them but they aren't very helpful to noobs. I still hate CTF. Why cannot I fly with the flag
I am loving the elites more and more and have found that blocking a sword slash is uber cool. Melee is going to play out VERY different this time around.
There are areas that need a lot of work. MENUS need to be revamped. They work but they could use some simplicity. Cross hairs, especially the pistol zoomed in, are very difficult to see. Like Robert said hit registration could use some work. This is a Beta but it should be noted that Net code needs a lot of refinement. A LOT of host changes as well as a lot of lag. I had a lot of head shots with the DMR in Swat that simply didn't register as well as a lot of nades thrown right at enemies go through them only to teleport BACK to the player at times.
Anyhow, this has been a lot more fun than most retail MP products. The Halo Trifecta is really great and the armor abilities really expand the game. Bring on the HUGE OPEN maps with vehicles and 32 players... oh, that is the new Activision version
I do hope Forge will allow a lot of flexibility. I can already can see how cool it would be to change abilities on the fly or even use more than one at a time. I also want a PRO SWAT mode where cross hair expansion is added for movement and body position. I can dream these into my economy check list? Anyhow I look forward to Invasion and the gameplay really makes me think COOP should be a blast. Hopefully we see 6 player coop, but I bet it will be 4 player and each one get a single armor ability.
