So many enemies and weapons firing on screen but the game runs buttery smooth, really great for a 120Hz setup. Lots of variety in the weapons but some of the characters are just re-skins of others. Could also do with more maps. 221 achievements on Steam, recommend if you like a game where your steadily picking those up and consistently unlocking new weapons and abilities. Also a good game to put on music or a video in the background and zone out with. Overall had fun playing in short and longer stints.
