Nailer

Nailer is a boss that was added with the release of the game.

Design
Nailer has a yellow square base with a turret on top. In 4 directions nailer has 4 trap launchers and has 4 twin auto turrets on the other four directions.

Technical
Nailer has a powerful triplet turret that has decent penetration. Nailer also has 4 auto twin turrets that fire at the closest player. Triplet Turret and Twin Turrets give it excellent bullet penetration. Nailer also spawns traps around him, where either trap turret can instead of spawning a trap spawn a minion. Minions look like small, yellow twins that continuously fire at the player. Although their damage is low, they can kill players fairly quickly if he will not kill them.

This makes a nailer a powerful boss which is a major challenge to be defeated in solo.

Spawning
Spawns by a randomizer.

Countering
Nailer has pretty high combined bullet penetration and large damage to kill a player without high bullet penetration fast. Its traps cannot allow players to get close, and do incredibly high damage to anyone who touches them. Nailer also has a lot of health. The main problem is that the nailer can spawn twin minions, which can easily kill an unaware player. Octo-tank branches do not has enough firepower to penetrate the defense of the nailer. Twin minions will circle around the nailer if there are no tanks nearby, meaning that incognito cannot defeat a nailer. So, it is incredibly hard to defeat nailers in solo.

Fight in groups of at least three players. One player will fight back against minions and triplet turret, while another one will penetrate its bullets and traps. The third player should deal the damage to the boss. But even then, it would require excellent coordination to defeat the nailer.

Nailer has decent speed, so do not choose very slow tanks. If you, however, want to finish off nailer in solo, minions and many drones are your only chance. Pick glass-build colony branch ( only if skilled ), or minion branches like splitters ( also, only if you are skilled enough in the coordination of many minions ).
