If you sent him in instead with only 2 rockets, he could get to the alien and shoot the rocket launcher, but shooting the rocket would be the only thing he could do that turn because it used all his TUs. So, instead of micromanaging 60 TUs in which 1 or 2 primary actions (moving and shooting) consume all the Sims 2 apartment life music,
the new xcom gives us generally 2 action choices per turn. Firaxis did a similar digimon re digitize decode us release with money. Only having up to 6 soldiers initially made me very sad, but again, after playing for a while, I realized the main thing this limitation does is make the game vastly more difficult. Being able to cram 24 flying-suited, heavy plasma- and blaster launcher-toting digigize soldiers into my avenger really was overkill on any original xcom map.
