I figured this idea is too awesome to be buried in that other threadnought and deserves it's own thread.

I was thinking maybe there should not be static teleports at all on gamma but players scan for the islands. Once you have coordinates for an island you enter them into special teleport beacon to get there (wrong coordinates will drop you in the ocean, underground or in space and you die). Once the advance team is on the island they build teleporter that lets you choose 1 or 2 existing teleporters (alpha, beta or gamma) where to connect (with limited range ofc). Once connection is made it works both ways. Making connection would take 24hrs and once connection is made cooldown for changing it would be something like 1 week.

Island scanning should take considerable effort (similar to artifacting but more than 2 coordinates and to get precise reading you need do to multiple scans on different islands and some manual math required). Higher value islands would be harder to scan. Island far away from the center can only  be scanned from / connected to other gammas.

Also I was thinking that Island could slowly move over time (several months for significant amount) so you cant just make list of all island coordinates forever and teleports in range would change. When teleporter on gamma island moves out of range from teleporter it's connected to the connection is removed. If enough island are made then it would be possible to allow island to drift out of teleport range from any island and become 'forgotten island' to be rediscovered later.

Only islands with teleport path to the island you are on would show up on the map (island info (location. teleports, etc..) is relayed via teleports like routers).

Player built teleport would be destructable but have high HP and maybe shield (maybe option to boost by player built power generator) too. And make big plasma burst (like plasma bomb but bigger) when destroyed.

Also limits on how many teleports can be on one island and how close together two teleports can be are necessary.

PS. I hate typing on this laptop.
PPS. I hate game desing, For every cool feature I can imagine I can come up with dozen ways to exploit it.
PPPS. Sorry if the constant editing is causing problems. I am slow thinker.
