You’ve done the donkey work.
Initially ‘just’ a reusable grenade - something you can throw with a timer and detonation
Your latest shows something that can be used as a grenade, or apparently with other modes such as the ‘activated’ device and countdown.
In itself a game format could be written around that - find a device, take it to a location and activate it
If you have a deactivate button then the defenders could save themselves (and perhaps then
Or expand on the device. Instead of just running a game that uses the device, programme a few game types into the device:
A maximum game time - start the clock at game on
Two modes on what happens if it is ‘defused’ - either the game ends and the defenders have won, or it can be rearmed and you have a game running back and forth until there is a successful detonation or game time runs out
Once you’ve started it’s more constrained by imagination than anything else
It does spiral though.
The attached photo is one stage of a test bed / prototyping device.
We have run a few events with devices that one of our guys makes, I bought an old ‘commercial’ site prop at an auction which needed some fixing, and it became a lockdown project to get it back running, identify its modes and then also produce new ideas of a combination of different game formats and the devices to run them

I’m not showing the rest, but the underlying software can go into a cased device or another ‘object’ such as your grenade/device
The screen & keypad aren’t required, just some form of input/output which can be keys, buttons, screens, audio, beeps, lights …. And other things
Post COVID I have a host body built for a new device which just needs spare time to make particular holes and assemble the components
