Grab psi powers to boost melee/str/agility/endurance/psi Research, get to level 3 then get the labassistant implant to boost to lvl 4 and research both exotic weapons The idea is to get crystal shard + viral proliferator +1str, 1agilty, 1cyb affinity(+psi agility power, the others suck) +(psi shield OR Neurogenic Cyb Affinity power)

It's mainly down to if the Navy player wants to go guns or tech at the beginning. Whoever has the most cyb affinity should probably take Modify and Repair over the other player - Marine will start with 1 with this build, navy will have either 2 or 0. Navy hacks and Marine takes maintainance (due to starting perks), and both can balance the other duties like Modify from there on. Very basic build that will spread out responsibilities between the two players. +1cyb affinity, 1energy weps OR +1cyb affinity, 1heavy weps (or a bit of both, or even exotic weapons if wanted) Either talk about which player takes like Repair or neither take it at all, your choice. Things (in parentheses) are optional in my opinion for the build. Note: ahead will be some suggested builds of mine. Exotic is fine to spread around as long as people only use the melee Cystal Shard, one of the best weapons, since ranged exotic ammo (worm clusters) is rare.

Energy weapons on the other hand have 'unlimited' ammo and are fine for everyone to take if they want. Try to have only one guy on standard weps, one on heavy, one on ranged exotic. Note: don't overlap ammo if you can help it in co-op. To see which starting perk options you have check out the System Shock wiki: I may update this later with pretty words to make it a bit less painful. Some mediocre grammar ahead but it gets the point across. Slammed out some quick builds I think would work, so if you have no ideas which modules to spend then check this out.
