Want to go far in escalation mode? A good healer is the key. This guide describes some tips, techniques, do's, and don'ts, and displays what you can do even when your team is only 2 or 3 deep. For the intermediate to advanced player, does not cover escalation basics, assumes you know how to get the healing gun etc.
Video is in 2 parts, 2nd part has hiphop music with explicit language (cursing). Must have annotations on, no voiceovers back then (sorry). There have been general strategy improvements to this map over time but still may serve to help you kick some butt in escalation.
Enjoy
