I played the first up to level 7. Having to fight horde after horde is tiring and boring.
The second game I read some negative reviews in steam and decided to skip it.
The third game seems to be in the right direction except for their art. They are relying on oversaturated graphics for some reason. Compare it to Doom / Doom Eternal, SW3's lighting and colors are pushed in a way that makes the screen hard to focus on the important things.
