It is a very good game. I played all of the part of serious sam and seriously fan of "serious sam 3" this part is no better than part 3 but still got in the line of best.
Many find this game irritating for repetitive issue. I think they don't wish to stick to sam for a while. They just want to finish it ASAP and go for next. I tell you what this is serious sam and there is something serious going on here All I can say is you may not find the fun part of repeating again.Besides while repeating they didn't take long time to get all the guns as they did as 1st time.
This one is finished, waiting for next part, eagerly !
