Fixed : Thanks to everyone for their help. The correct regex was

/(.*?)Player "(.*)" \(DEAD\)\ \(id=(.*) pos=<(.*)>\)\[HP: 0\] hit by Player "(.*)" \(id=(.*)\ pos=<(.*)>\) into (.*)\((.*)\) for(.*)damage (.*) with (.*) from (.*)\s*(.*) | Player "(.*)" \(DEAD\) (id=(.*)) (.*) killed by Player/

I ran the above on a larger log file and the returned data was as below

[0] => 22:09:04 | Player "GigglingCobra52" (DEAD) (id=BE2ABB8084EEC781014AC8E6B5C88A5A90F855BF pos=<1658.8, 15056.8, 451.4>)[HP: 0] hit by Player "Cogito8434" (id=26DE70CAEF00AE579AF8CA21ED3F1648DB316F1E pos=<1659.4, 14990.8, 441.4>) into Head(0) for 36.7336 damage (Bullet_308WinTracer) with M70 Tundra from 66.7822 meters

I can now use the returned array data and pull info I need. Thanks again for everyone's help in guiding me how to figure this out
