yup, you either played conservatively and carefully, saving APs, using over-watch, multiple over-watch angles overlapping covering field of fire. Make one mistake tho and poof all that time and hard work just went down the drain.
the alternative was to nuke the crap out of everything, with destructible terrain, High Explosives, grenades you simply just went Postal on the environment . The tactic was limited to your supplies, cost and any civilian casualties you will incur. not to mention fewer salvage.
2 ways to play, most players did a mix of both. Removing ammo, removing APs etc just dilutes the tactical aspect of the game. Love the graphics but i will not trade graphics for console gameplay. Here's hoping Xenonauts comes good and we will have both XCOM type games and the players can decide which is worth your time more.
