Any advice for the Mantis C? I have no idea how to use this thing. I have no idea whether to use the mantis or lanius for boarding early on.
Use both and as soon as they warp over put the mantis in a different room. Once someone starts fighting the lanius drop a stun bomb on it. This gives it time to drain the air and kill off the enemy/enemies before they can hurt it too badly, while your mantis is happily slicing and dicing elsewhere.
Probably faster to just leave them both in the same room and let the mantis suffocate, and faster = less damage taken, which = more scrap for upgrades. You have a clone bay after all.
But yeah, mantis C is really... not so good. Mantis b is the second best ship in the game so I guess c can't be any better (or the game would be super easy) but it just feels like such a pointless ship.
Five games with the rock cruiser.
FIVE GAMES trying to get that fucking 'Kill a burning enemy' achievement. Denied every time due to some BS.
No non-missile weapons and out of missiles? Check.
Get fire drone, have enemy crew keep running from rock crew until the ship finally explodes? Check.
Have enemy repair their ship too quickly for me to make use of the fire drone? Check.
No fires caused by any of my weapons, despite the game saying they can start fires? Check.
No teleporters in any shops ever? Check.
The fire one is almost impossible unless you get a fire weapon, and a teleporter, and make it to the boss (the enemies in the guns have nowhere to run) all in the same run, or manage to set the whole ship on fire.
It's really a PITA, and it's worse because the rock ship is (at least imo) really annoying, and the other achievement is even more random.
