Serious Sam Classics: Revolution "Developer Rage Achievement" is acquired by killing a dev from the game.
How to Get the Developer Rage Achievement
This achievement goes by chance so here's few tips to help the chances.
- Play the game a lot, i currently have 180+ hrs on the game.
- Check multiplayer mode often since you have to kill a dev in "Versus mode".
- Host a server and wait which helps a lot, the servers are usually inactive so good chance they will join you.
- Ask devs in the "COMMUNITY" section on SS Classics Revolution if they can help with it or even ask if you need to test something in "versus mode" make sure not to lie tho.
- Keep up to date on SS Classics Revolution updates most likely some devs would be online after posting info.
I love SS Classics Revolution which was my favourite PC Serious Sam at one point because of the content so i played like everyday which helped get the achievement, going in with good intentions can also just help you get it quicker and without you even noticing.
