I did some searching but we don't seem to have a catch-all for this yet. So making one now.
To start it off. Where the heck did this game come from? I heard the name "global agenda" every now and then from various sources. But until I walked past the booth at PAX and stopped in at a demo PC I had no idea what the game was about. Here are my impressions from playing a couple rounds in the Expo hall:
The game seems to be a mixture of TF2, Tribes and Planetside. Players receive a pool of points which function a lot like certs from Planetside. The pool is limited and you can use them to improve various aspects of your character. The PAXer sitting at the computer was kind enough to explain all this this to me before he left. In this case my heavily endowed infiltrator (think scout, sniper and spy combined) was specialized for melee and stealth, with a little sniping on the side. The abilities trees seemed to have a good amount of diversity. No doubt there will always be "pro" builds, but there is a lot of room for tweaking. The other classes which I didn't get a chance to try are a more general soldier. A well armoured TF2 esque heavy. And finally an engineer "robotics" class that looks rather a lot like a 40k Techmarine.
I got into a round and started mashing buttons in lieu of a tutorial. Button 1 was this giant sword. Melee combat is fairly simple, LMB to slash, RMB to block. Blocked hits are reflected back and hurt you instead. But melee shields do not affect guns, so if anyone turtles just back up a step and blast em. Button 2 was a rifle. Unscoped it is a fairly damaging autogun, but nowhere near damaging enough to take on enemy heavies. Scoped in it performs as a fairly inaccurate sniper rifle. Though to be fair all my cert points were spent elsewhere. I forget the order of the rest of the items, but they included a TF2-esque spy cloak plus sprint, a jetpack, and the classic remote detonating "c4".
Getting into combat was quick and easy. The gamemode we had going was the typical area capture plus team spawn tickets model that a lot of games use. My character felt a bit gimped at first, until I got into melee. With a lot of cert points into swords and melee damage I could take down enemies in about 4 hits. Enemy heavies required a bit more dancing.
One thing I didn't like about the game is that each piece of gear can only be used ONE at a time. That means to use the jetpack you must put away all weapons and press LMB to fly. Cloak is the same way, hold down LMB for invisibility. Gear is all energy dependant and every item shares the same pool in lieu of ammo or charges.
Gear customization is varied and apparently crafting based. There are PVE missions you complete to gain money and crafting parts, though they were not in the PAX demo. Somehow the player before me had managed to give my female infiltrator a Santa beard of all things AND a wizard hat. Lots of differently shaped and coloured armour plates on show, thought the overall look of a character never changes so much you can't identify class at a glance.
So thats about it. Ask a question and I might remember some more of it. I will certainly keep my eye on this one. This is the kind of persistent team FPS I have been craving ever since planetside when downhill.
