Given the question: Given the below context:  A man is trying to escape from the titular Cube. Upon entering a trapped room, he is sprayed with a liquid that rapidly melts his entire body. The rooms in the Cube are being monitored from a remote observation room by two technicians, Eric Wynn and Dodd, who are unaware of who their employers are. The pair are shown playing chess during work, whereupon Wynn demonstrates mental calculator abilities which he uses to predict Dodd's moves. Wynn has also a hobby of drawing comics that portray him and Dodd as superheroes. Wynn and Dodd are ordered to record the dream of a subject, Cassandra Rains. In her dream, Wynn sees Rains captured while walking in a forest with her daughter. Rains wakes up in the Cube and meets the other occupants: one of them, Robert Haskell, has the same tattoo on his forehead as the soldier who captured her. However, Haskell, like everyone else, only knows his own name and has no recollection of his former life or how he got there. According to what Wynn and Dodd know, everyone in the Cube faced a death sentence and volunteered to partake in psychological experiments instead. Rains' consent form, however, is not found in her file. The captives venture through the Cube, testing each room for traps by throwing a boot in it: most of them are killed anyway until only Rains and Haskell remain.  Guess a valid title for it!
The answer is:
Cube Zero
