I have seen many complain about lack of VOIP as standard and nobody communicating as a result. As a PC gamer in Europe, I must say that other titles I’ve played that supported VOIP, it is rare that anyone used it, and when it was it was mostly used for whining or harassing rather than tactical communication. Maybe the US and/or consoles are different, but I don’t care for VOIP.
Anyway, after playing Brink for a few weeks I have made a .cfg with sayteam binds, and I have had decent results using it. A piece of paper with my comms keys drawn up with a note on each is vital for learning the setup.
Buffing: When I run out of spawn with an engineer and don’t get buffed, I hit my weapon buff please bind. It mostly works, people even turn around to buff. Some players change behavior after a few messages, actively looking around for buff targets when spawning afterwards. I think many players just go into solo mode mentally - but start communicating and they change outlook, helping the team becomes top of mind.
Pushing: when we fail to break a choke, I tell people to gather up and prepare to attack in a push together, and ready flashbangs. I then have a push now! Throw flashbangs! It often works. The effect sometimes persists, where teammates seem to become aware of team member positions and gather up before pushes afterwards (the player icons on HUD is probably a great help here).
Flanking: I have binds asking for flanks, taking high ground (like parts of sec tower) or attacking from below (like first part of reactor). It almost always work as at least few players will respond. Surprisingly, it seems to work best when the flanking route is difficult or only a few players are teamwork oriented, as I’ve seen the entire team flank, which greatly reduces its efficiency as you don’t get a crossfire going. I need to modify my binds to adress this issue.
Objective awareness: I have a bind asking to go for the objective and bypass fights, and one warning of incoming to objective, defend it. Both seem to increase focus on objectives and reduce the amount of playing seeking kills for kills’ sake. Again there’s often a clear top of mind effect.
Politeness: I wouldn’t say I didn’t communicate before. But it was too often after getting frustrated and it was along the lines of “stop plying tdm noobs falkn them!!” (misspelling intentional). This had very little effect. Of course I communicate more readily with binds, and maybe this is why they work better. But I suspect that the less hostile tone in my binds make people more receptive.
Has anyone else tried communicating over chat and had success with it? I strongly recommend that you try this.

Grumpiness aside I do wonder just how much work it would be to enable a lot of this legacy stuff. Do developers really save that much time by dumping all this? I can’t imagine it would be more than a few hours of coding to get the core of this down if not all of it.
