Started playing this now, seeing as I got bored of BF3. And it's a proper laugh with friends on TS.
It can be a bit daunting at first, there is no tutorial or anything like that. It just throws you in at the deep-end. Luckily, a couple of friends guided me through it. And I'm now getting used to all of it. Mainly playing TR at the moment, but I'll think I'll start multiple characters once it goes final.
Only played a few of the classes - Medic, Light, Heavy and Engineer. Thankfully a lot of the tactics I learnt in other FPSes are easily transferred so I have no problems with infantry encounters (easy to a kill streak if you flank the enemy). I find the lack of grenades a bit weird, I don't like the idea of buying them each time (or whatever you call it).
I do like the idea of limited ammo in vehicles, as it adds a new spin on that element. Loving the Sunny and the Prowler. Certed my Sunny to be able to deploy and become a spawn point for my squad is really handy. The Prowler is awesome, I can see me spending more time in that. TKs come way too easy in vehicles though. They need to do something about that.
The whole squad/platoon thing is awesome. We have like 4 squads in a platoon, and we had these massive ships that would ferry us from one place to the next. It's a frigging sight to see 30+ people unload out a ship and storm your base.
30 mins can easily turn into hours with this game, this is a good thing IMO, well mostly a good thing! :D
