I've only played the first couple of bounties, but so far I'm really liking this. As per the trailer, it captures that 80's violent action film vibe really well.
The 16-bit style graphics look really good, and the the synth soundtrack is great too. It has tons of character.
Gameplay wise, it's a run and gun platformer. You fire forwards in the direction you're facing, you have a jump, a dash and a thrown weapon, and can duck or take cover from enemy fire in doorways. You have a pistol weapon with infinite ammo, and can pick up more powerful sub weapons with limited ammo, or a melee weapon. Each bounty (level) is a short action platforming section that leads up to your target, which is a mini boss fight.
It's fairly straightforward, but is smooth and plays very well.
I've only tried one player character so far, so don't know if they have gameplay differences.
It's Epic exclusive on PC at the moment. With the £10 coupon thing in their sale going on right now it only cost me £7.99.
