Martian mode two point oh

[Sundance]

it's sort of impossible to disguise yourself as an alien would help with recognizing your comrades

This is true, AI and borgs would have an active part in defending humans from what clearly is not human

the only huge concern i have is idiots suicide bombing the mothership or metagaming jerks in pods running around with lasers 2 minutes in and destroying the mothership before anything can happen

Both are two things I have considered.
The first may not even need an idiot suicide bombing, but a HoS who's armed to the teeth with a jetpack, the ship may not be able to target him. I thought of an upgrade for the ship (one of few) which would spawn "chasers", basically blob like critter when comes in contact with a player does 1) toxic damage? 2) slows them down? (again open for discussion)
The latter problem is not an issue, but rather I would see that it is encouraged so that idiots would realise that taking on a mothership on their own even in a pod is batshit retarded. Martians work as a team and the station would be required to work together to take them down, vigilantes would be biomass-fodder.

would definitely need to give them some sort of aura where people within their field of view can't suicide/succumb to prevent them from getting biomass though; also i'd imagine the amount of biomass necessary would vary relative to server population?

This is fully activated martian torquebow, the weapon they spawn with. It is a 3-shot taser. When used point-blank, it has the same effect as a vampire bite, causing potential stun but more importantly: stops a player from succumbing.
And yes, biomass would vary.
