Tried it out last night.
First impressions are not brilliant. Lag is horrible, differentiation between sides is poor making it difficult to even work out who to shoot and the "new player" experience is pretty much non-existent.
Will give it a few more goes obviously but so far, not so good.
You chose a REALLY bad night to try it out. The servers were getting hammered, especially if you played on Miller. The warping was outrageous and a lot of the nametags werent bothering to draw. I flew over a friendly base and had every friendly AA gun open up on me.
your best bet to get a proper taste of the game:
1. Create a character NOT on Miller, one of the HIGH servers.
2. Choose a class you like - I would suggest Light Assault, because they have jetpacks.
3. Jack your brightness up.
4. When you spawn in make sure you are in Indar or Amerish. open up your map. Hover on one of the deploy signs and see what the ratio is in the region. Ideally you want a 50/50 ratio of your guys and an attacker at a big base, like a bio dome. Hit deploy.
5. Use your backpacks and get on top of stuff. Your aim is to get to a flag point - A,B or C. If its green its yours, if its any other colour its turning or is an enemys.
6. Shoot anyone that does not have a nametag.
7. when you respawn choose a sunderer/spawn close to where you died. If the sunderer is next to a building away from the base look in there, there might be a transport gate inside.
8. Expect to die, a lot. Aim for the head. Start trying out the different classes.
Have fun.
