Team Fortress 2 has been an interesting mess since the Engineer update. You can trade your sentry gun’s ability to upgrade for ridiculous building speed or its self-targeting for a remote control, but the greater change is letting all Engineers pack up their buildings and move them. Fully upgraded sentries are popping up all over the place, fast, while they are also being shot down faster than they can be reassembled. Two weeks ago, you might plead for a second Engineer, and now you’re considering moving to a server that caps them. You can be annoyed at the insanity or embrace it, being your team’s seventh Engineer or picking a class to counter them.
The attached achievements are actually healthy. I am used to seeing achievements for aberrant gameplay or freakish occurrences, like getting mid-air melee kills while rocket-jumping or encouraging medics to attack instead of using an uber-charge. The Engineer achievements are largely for things you should be doing anyway, and most of them encourage teamwork, particularly between Engineers. There are achievements for helping someone else build, for upgrading their buildings, for healing their buildings, for saving them from Spies, and from getting Engi-Engi kill assists. There are achievements demanding dispensers and teleporters. The Wrangler (remote control) gives an Engineer the Sniper’s narrowed focus, but the rest rewards a utility class for being team-focused. Excellent!
