The Return Of Optimus
The first bad guy Optimus must handle is Ravage, one of the most loyal Soundwaves spies and one of the most deadliest Megatron's machines. The cat it depicts is probably panther, although it could also be a jaguar. Although Ravage operates best at night, this time he faces Optimus at open in the middle of a day. So maybe terrain and curcumstances are not on his side, but his sharp claws are still very deadly weapons. Ravage is glued to Prime, following his every step, taking every chance to get his claws into Optimus torso.
Controls are logical and clear, but the movements needs to be redone. You walk around with WASD keys, while you can use 'J' and 'K' to kick or use a sward on your enemy. 'I' transforms Optimus into his truck incarnation so he can get away easily if it gets tough. Also try 'U' and 'O' keys to see some more attacks.
When (if) you take your enemy down, you will be promoted to a bonus level, in which you drive Optimus' truck on a three lane road, trying your best to avoid head collision with the road obstacles. You can't shoot, transform anything like that. You can only drive between obstacles by changing lanes rapidly.
After you finish up the bonus level, you may expect to fight some other Decepticons in battle arena. The concept as well the controls remain the same, so the game feels a little bit repetitive. If you turn a blind eye on that and terrible controls, you will get a decent arcade fighting game with transformers.
