Notes from Higby's TwitchTV stream 31-10-2012
Thought it might be good to have it all in one place.
There was a stream with the creative director tonight which showed off Amerish and also addressed other stuff that'll be in the next patch. I took some notes:
Amerish will be in the next big patch. (we knew that
Base design will be different there. More defensible, more chokepoints. Also more unique base design. Might carry over to Indar and Esamir later. One example of chokepoint is a bridge over water... which happens to kill you.
And yes, there is water on Amerish.
Respawn timers have been increased (up to 10 seconds I believe). Biolab ownership will reduce these respawn timers.
Number of bases on Amerish is somewhere between the number of bases on Indar and Esamir. More than Esamir, less than Indar.
Some of those bases have a more linear capture order; you have to move from A to B to C. Other bases can only be reached by air due to their position on a high mountain. There will be quite a few mountains on Amerish.
Some bases are quite vertical, which should keep tanks away from the spawnroom and turn it more into an infantry fight.
Changes to metagame:
Tweaking of resources to make them matter more.
Facility ownership will give benefits.
Dominating a continent (holding all capturable regions) will give a worldwide empire buff.
You will be able to spawn on your Squad Leader with instant action (cooldown 30 minutes).
You will be able to spawn on any hard spawnpoint closest to your Squad Leader.
Squad beacon will now only be available to the Squad Leader. It doesn't need to be equipped; it only needs to be certed into. It will also cost no resources. There will be a 5 minute cooldown on using it.
Squad vehicles can be spawned on wherever they are in relation to you.
Sunderers can be spawned from any vehicle terminal but will be less spammable. Their deployment range is now 100 meters, which might increase later.
[EDIT]"Sunderers will not be able to be spawned on terminals , if there is another sunderer deployed in a 100 meter range (which is subject to future changes and tweaking)"
Defender gets bonus experience for all actions performed during defence. Bigger facilities bestow greater bonuses.
Attackers do not get such a bonus, but do receive a large experience boost upon base capture. Again, larger facilities will give more points.
Performance and bugfixes:
As always, performance and bugfixes are worked on.
Amerish might run slower since it has not yet gone through some optimisation that Indar and Esamir did go through.
Grenades will no longer stick to your hands.
Painfields will return to spawnrooms: no more enemies camping a spawn that cannot be entered.
Lock-on missiles will hit more often due to fix to splash damage.
Restoration kits will heal even after switching weapons.
It should now always be possible to spawn on a Sunderer.
From next patch, it will be possible to stream the game to Twitch.tv through the game client. It has an in-game streaming function to do so.
Battleranks now have icons, and will unlock things like extra loadout tabs and Squad Leader Abilities.
The game uses a new font.
The repair tool now has a heat meter. Heat must be managed now in order to prevent overheating. This is done to prevent continuous repairing.
MBTs will get more powerful secondary weapons. Additionally, extra certs will unlock a dedicated gunner slot, which has access to more powerful main weapons. Prowler and Vanguard will likely have a full crew of 3, while the Magrider setup probably necessitates a limit of 2 crew slots. This will most likely happen after launch.
New kinds of facilities are being discussed (interlinks etc.).
Squad Leader certs will be broken up into different categories over the next few weeks (communications, logistics, command tools etc.) as well as Squad Leader abilities being tied into Battle Rank.
MAXes may get more hitpoints.
New capture mechanics are also being discussed (including CTF mehod).
Heavy weapons (Lasher, MCG, Jackhammer) updated.
Mission system is going to be phased in. Squad Leaders can unlock it. Currently possible to place attack and defend order on the map which are visible to the entire faction.
Number of AA turrets will be reduced. Additionally, it will be easier to spot AA location/direction from the air. AA will also do less splash damage.
