While this has been suggested before, I would just like to bring it up again. The idea for the Engineer Glove weapon would be to build a temporary turret to attack (similar to a gun puppy). How long the turret lasts depends on how long you charge the weapon. (Max Charge: About 30 seconds)
That's about all I have to say (I'm terrible at this), feel free to add your own ideas!
How many turrets can you have out at the same time? Only one?
This would go well with this old suggestion I made some time ago : ) http://forums.spiralknights.com/es/node/55891 Though someone suggested that there would instead be a "wrench" and not a glove for that, which then you would be able to use to dismantle the turret or defend yourself - though at a really low damage, only worth due to low knockback.
The "glove" should count as a bomb so we can have a good CTR for it also i you didn't mention a basic attack so yep that is plenty "bomb like". As for it being some what OP to spawn a bunch of turrets you should only be able to charge it if you do not own one that is still alive. Also make another crafting line that spawns mecha knights. The only real problem with this is they are ment to cost 5 energy. (boo lame)
