i'm only going to list what i would change

A it would be the level 4 but requires 600 metal to upgrade from lvl 3 to this lvl 4

if you don't have wrangler no lvl 4 for you (jk) it would basicly be a lvl2 minus one barrel - 75% damage but it would have the fire rate of a mini sentry and it would have 25% less ammo & +50% sapper removal and repair time (hit it more)

if you do have wrangler when you arn't controling it it is an absalute dud dosen't move doesn't shoot. and instead of the regular moving animation were you put it in a tool box it follows you around the map and when you die it blows up like a rocket but 20% less damgae and if you would have had crits when you died the explosion is a crit and/or a mini crit dependant on witch you had

anyone else have ideas?
