This plane is the beginning IJN tech tree heavy fighter, available via a mission for 5 tokens. My initial impression, after slogging through the missions, is that it's much better than I expected.
The fully elited version features a single 37mm cannon and a single 20mm. There is a rear gunner with a 7.92mm gun. It carries two 250kg bombs for a cumulative damage of 8800.
Flying it reminds me of the german Bf 110 C-6, except this turns much better. The guns pack a good punch, and with the surprising maneuverability, it can handle the 'melee' around a cap quite well. I tried it against bombers and a player bomber and it had no problems with them, although it was beginning to get sluggish at the higher altitude the bomber operated in.
You get a free camo scheme with it, which quite honestly is garish in green, yellow and orange, but it's free. Pilot + gunner with 1 skill. Overall, a big thumbs up and I look forward to the rest of the line.
