I'll say UFO. I just can't shake this image I have of whoever came up with the TFTD races just throwing darts at a dart board with peices of paper stuck on that have random attruibutes on. Designer-type-guy: Throws dart, hits TENTACULAT DTG: "Is like a..." *throws another dart*, gets CHRYSSALID DTG: "Except it can..." *another dart hits the paper with FLY"
Well, according to what I saw, the gains stack ( just talking about weapons here), first medium weapons computer added 20% accuracy to my valk, second added 10% and the third added 6%. I also put on some small weapons computers and they increased the accuracy too, but then again, that's just what the equip vehicle screen stats said. I like using 6 Agents in real time. They are easy to control but sometimes you have to wait for the aliens to move around if there's a huge group of them.
