I recommend you set up RD binds since almost all the servers use RD. Go into your Unrealtournament/System/InfiltrationUser.ini file and edit it in notepad. Go down to where you see all the different keys on the keyboard with a "=" after them and then the bind. After the = sign, type this:
mutate direction <the text u want the bind to say> %A %N
If you want the bind to also play a sound file like "Area is Clear" then you need to put a %S1 variable in the bind also. the "1" is a hexadigit (0-F). If you are using Voice pack #1, then here are the different variable and the sound file they play:
%S<hex-digit> tag
Voice Pack 1
%S0 Fall back!
%S1 Area's Clear
%S2 Go Go Go!
%S3 Hold Your Fire!
%S4 Move
%S5 Cover Me
%S6 Go
%S7 Contact!
%S8 Frag Out!
%S9 Clear.
%SA Hold This Position
%SB You Guys Comin or What?
%SC Got Em!
%SD Man Down!
%SE Got Em!
%SF Weapon's Dry
%SY Acknowledged
-----------------------------
Putting it all together, here is an example bind:
1=mutate direction Enemy Spotted %A %N° %S7
When the 1 key is pressed, your soldier will yell "Contact!" and the bind text will read:
Enemy Spotted WNW 30°
