XCOM 2 introduces a new player state, called Concealment, which adds an element of espionage to the game. Just remember what game you’re playing when that “perfect shot” flies right past your target.

Yes, players should still take any shot with a high chance of success. We’ve lost count of the times we’ve whiffed on melee attacks with 90-plus percent projected chance for success or fired helplessly into the air when standing just a few feet from an enemy. But any experienced XCOM player will tell you the series’ chance-to-hit percentages have always felt laughably inaccurate. Telling you not to trust the statistical component of XCOM might seem a bit counterintuitive. But hopefully we’ve rounded up enough information for new XCOM players to get started down the path to success. Some of the information below might seem a bit obvious to experienced players.

Fortunately, we’ve already slogged through dozens of battles, figuring out which strategies from Enemy Unknown are still effective in XCOM 2 and which tactics need an update. There are new enemies, new soldier classes, new facilities for XCOM organization’s mobile command center and loads more. Thousands of players are struggling with 2K and Firaxis’ latest tactical strategy game, trying to make heads or tails of all the changes introduced in XCOM 2.
