Photons remove X turns in limited games

eMissles - destroy a fig when there destroyed. Essentially same as probe but really expensive.
Level 7 planet - super expensive - implodes a warp and/or creates a new warp - do a bit a of game scaping to creating your own tunnel or make an enemies harder to defend. Maybe make a backdoor to Terra.
alternatively blow planet and destroys everythings at sector level also - all ships/players - i.e. 5mil ore.. kaboooomm
Gold Aliens that leave the figs on the planet...
These would fundamentally change the game and will cause a whole level of whinging

oh and the sysop tools that would allow game event push notifications to a script. So it could detect things like player enters a sector, or cap's a planet, then you could trigger something else in game. Things like, you detect player cap's a planet, make more aliens materialise or something.
