About This File
This is one of the best of the TAB Series. This one is called "TAB27: The Secret of the Doom Ooze." As The Space Marine, you must once again infiltrate one of the Evil Mastermind's secret bases. You arrive in an underwater cave via super submarine. From there you must find the transporters to the underwater base and then it's all downhill... you have found out that the lava for all Doom levels is being mined under! Helpful hint: While underwater make sure that you have a radiation (oxygen) suit on at all times-- you may be a brave warrior, but you are invulerable. Also be very careful in the engine room. One other thing, save often!
