A few power-ups/monitor ideas.
I have a few idea for gimmicks if you guys are still looking for some. One of my idea is called "Warp Engine"
It's idea I had for the Sonic Worlds engine (Made in MMF2). This gimmick would be best suited for a machine-type level.
Anyway, the Warp Engine is sort of like the Warpstar. It uses some features of the Warpstar. Sonic hops on the warp drive and rides it to a certain point. Could be a flight leading to the bonus area, or a hidden area.
Another idea of mines is called "Protection Shield". It basically like the normal shield, but it has HP. That's pretty much it.
Whatever name you choose (personally, I like Binocu), Binocu is a enemy that serves as a "watchdog"
He'll sound an alarm when you get in is vision. Any near by enemies when swarm around you. Basically, he's a walking alarm system.
Description:Murder-E1 is the first of 3 series of Eggman/Robotniks A-class badniks. These badniks are powerful, but can be taken down in 3 hits.
He's deadly saw making hard to hit, he'll eventually get tired of swinging at our mighty blue hero. That's the chance to attack.
Description: Murder-E2 is a claw based version of E1. E2 swings with 3 powerful claw attacks. Two Left and right side slashes , then ending his murderous combo with a downward slash using both his claws. Just keep your distance and go in for the kill while he's recharging/resting.
Description: As his codename suggests, he uses hammers. Hammers has 3 attacks. The first is the same combo as Claws. The second one (Hammer Wave is he pounds the ground sending out a shockwave that travel in both directions for a short time . He last attack is devsating for a mid-boss. Hammer Crush is an attack that summons sharp stalagmites when Hammers slams his hammer fists into the ground. The Shock is so powerful that it pops Sonic in the air.
I'll post the concept art once I get it scanned.
