Hey guys just a few ideas, looking forward to some feedback.
1. the Sentinel's
This mob was previously know as the guardian, I have since then done some editing and got rid of the ranks.
The sentinel's are tall robots about twice as tall as the player. They now attack the player on site. there right hand is a small blaster which shoots out Iron arrows. Due to there armour the sentinel's can be hardly damaged by wooden weapons, anything above wood such as iron and steel will do more damage to the sentinels. They can be found on the surface and at any depth.
2. Zombie engineer.
The zombie engineer is an interesting mob, he does not crave brains as much as his normal zombie relatives instead he places down offensive and defensive blocks, waits until the player is dead and then feast upon the brains.The best tactic to kill a zombie engineer is to take them out before they place a sentry turret, on there own they are weak and don't have a defence. if your facing several Zombie engineers then you may need to use an explosive weapon, or just invest in a lot of cooked fish. They can be found on the surface day or night and at any depth.
3. Nemesis
The nemesis is a mob that is covered head to toe in a pitch black material, the only way to spot them is there glowing red eyes, some people think they origonally created the spiders of total miner due to there eyes and nerve wreaking screams, the Nemesis however lets out a lower and longer pitched scream, due to them been pitch black in colour it would be easy to miss them at a distance, its only when they close in however and you hear them breathing. you find these guys in the caves alone. they NEVER go to the surface. unless its the world of the beast.
