I was shocked when I read Implement "Redemption" upgrade on the development progess page.
Redemption has never been viable in any possible situation.
2. Frustrating for both sides (!)
3. There were much better options (since you had to chose between carapace, regeneration and redemption)
You are deliberately adding a RNG into a FPS game and everybody hates RNGs.
The skill level is already pretty low with lacking movement options and Redemption is just another "noob upgrade".
The idea I had is making Redemtion a castable buff for the alien commander (like in savage 2) which costs energy and lasts 2-3 seconds.
