Etnam mod has the option to stick a grenade to a person. You need to bind a key, select nade as weapon and then be in close proximity (next to) person to stick it to the player. The nade then times out and explodes. It's not a great gameplay addition, but it's very hard to place and very fun when actually done. I'm not sure I'm requesting it more than suggesting it. It wouldn't be something that is very useful, so I'm not sure it's worth the code? Etnam mod does have quite a few fun options and I see that you're not trying to copy it. Silent is by far the best server mod to manage, keep up the good work
