Sega has announced a sequel to Transformers: Human Alliance arcade game during Amusement Expo 2018. Titled as Transformers: Shadows Rising, the cabinet is modeled after Optimus Prime as opposed to Bumblebee for the original game.
Arcade Heroes has the scoop:
“With the sequel, Sega has opted to focus on Optimus Prime. Several signs were posted on the machine saying that the software was 75% complete but the cabinet likewise seems to be lacking some production level finesse. The Optimus head looks spot on and has LED eyes; it also has decorated mufflers on each side. But different from the Deluxe version of Human Alliance(which uses a molded bezel), the back of the game is flat and currently uses frosted acrylic for the windows. The game’s title is only found on the side art instead of a noticeable marquee. Overall feels like there are a couple of elements missing but I would expect this to look different by the time the release rolls around.
Software wise, the game plays like Human Alliance – there is a strong focus on co-op play, larger enemies require one to hit the targets quickly to break the attack, there are swarms of smaller enemies to fight, the voice acting is perfectly cheesy and there are Autobot assist sequences (Coop Battle as the game calls it) where you must hit all of the markers that appear to help the Autobot win the fight against the Decepticon. You (and your companion, if playing 2p) are given a letter grade depending upon your performance during these sequences, just like before. A story unfolds as you play along although chunks of it are certainly missing in this build. You also encounter Dinobots.
Graphically the game is a noticeable improvement over Human Alliance. It appears to be running at a higher native resolution; textures are sharper, character objects have more details, the colors are much more vibrant, there are nice smoke & explosion effects (now with more spark particles) and the game seemed to be running at the necessary 60 FPS. The lighting engine is better, with crisp shadows and less bloom than I recall from THA. I have no idea at the moment what hardware it is using but it seems likely it would be a step-up from the RingEdge 2 that THA ran on.”
