The Rumbler is the newest addition to the Big Daddy roster, and has a completely unique combat style. However, even in Elite form he doesn't change one bit over the course of the game. To change this, one could borrow from his old model, the Slow Pro...
- Level 1: Handyman Gene Tonic
- Level 2: +Damage
- Level 3: Danger Close Gene Tonic (see here)
- Level 4: ++Damage
- Level 5: Decreased enemy explosive radius
Nothing much at the start. Instead of just standing on the spot and shooting you, though, Rumblers should try to get some distance between it and you, throwing Mini Turrets behind him as he runs away. He could also crouch behind cover while firing rockets at you. If you're the one running away, he could throw a Mini Turret from around the corner before breaking your cover.
Elite Rumblers should have their advantages boosted, while maintaining the same general strategy. To suit this, they could both: A\ Wield the Slow Pro's giant hook thing to buff his melee attack. It wouldn't deal nearly as much damage as a Bouncer's, but it could be able to send you flying backwards, allowing it to shoot you from a comfortable range, and: B\ Have a wider variety of Mini Turrets to vary his attacks:
- Liquid Nitrogen Turrets freeze the air around them, slowing enemies down and make them more vulnerable to damage. Used against groups and fast enemies. Hold a gas tank and a series of connected hoses.
- Relay Turrets don't attack the player, but could guide the Rumbler's rockets around walls and corridors towards you. Used against enemies behind cover. Noticeable thanks to a characteristically large antenna on top of each one them.
- Mortar Turrets fire explosives, just like the Rumbler, but instead of hitting you directly, they fire a Frag Grenade into the air; which falls back down onto the designated zone. Used in open spaces (preferably with a high ceiling). Have a very short and large cannon-like weapon.
And that was the Rumbler. After this, I'm doing the Alpha Series, and then... you'll see.
