Thank you Apex!
I often challenge to get over the limit of GR.
In past, I made TvT gametype "Hostage Rescue". One of the team member is teleported to enemy team base with no weapon when startup 7secs after.
Each team try to rescue their team mates and prevent enemy rescue. Hostage players try to escape to their base. If hostage escaped (over 10m from the base I think), enemy can kill him.
"Hostage Rescue" is very fun in MP. But it doesn't work well in some maps. Hostage player stucks in the ground sometimes. I couldn't fix it and removed download link.
Finally, I want to say is... nothing!
I am a modder. I make mods. If you want to fix it, please fix it, Tinker.
