Wheel Gator Dinosaur Tank stage is harder then the previous. It is longer and acquires more weapons to master, specifically the strike chain.
Remember the harder you press the shoot button the longer the chain will extend. Know this when performing a segment jumper to get to the capsule of Dr Light as shown in video. This is probably the hardest segment of the video to do in one try.
The next part is a bit easier. Remember you CAN get hit in the robot and take NO damage. After the robot part head up the ladder and see the HEART. Make the enemy shoot the 3 projectiles at Mega Man X. Jump into the FIRST one, then quickly dash on the spikes and to the HEART.
Finally the end of the level has quite a few enemies you want to destroy or dodge. Use the Strike chain on the shield enemies. X - Buster on the flyers.Charge your shot for the flyers HIVE then x buster shot the next enemy.It is pretty easy from there except 2 last parts.
There will be a "guard enemy" at the boss door. Watch video and fall down while equipping strike chain. Blast him directly under him with it very fast and jump into the boss door ! Congratulations on taking NO damage in this level FAST ! Now take a break and get ready for a REAL Boss !
