Played long enough to get enough engy achievements that I unlocked all the new weapons and crafted the new wrench (scrap metal + ambassador). Lil' sentry + FJ is THE way to play attack engineer. The wrangler + big level 3 is good for defense. I like that the engineer has a decent attack option.
If you're on a server with a bunch on engineers, get everyone to build their stuff in front of spawn and then everyone upgrade. Send one guy ahead to make an exit and everyone teleports their stuff to the front. I should have taken a screenshot of 7 level threes right in front of spawn.
There's also a neat glitch, if you build a level 3, then go into spawn and equip the gunslinger pick up your gun and put it back down, it'll be a level 3 mini. It doesn't work all that well, but it sure is funny to look at.
