Reply to Robertjr114: Choose a strategy Build / Curse / Destroy. Then customize your deck towards that goal. It's a system, not just a card. I have >1000K wins to backup this up. I have many good opponents (or friends now) who uses basic cards to win. This is pretty similar to Hearthstone.
Why they limit the shop to teleport & usually once? It should be free & as often as you want. They also should explain retreat onlyonce after clearing dungeon & putting stat pts right from the start fr. the tips or tutorial.
Just play last mission 23 again (Should start all over from mission 1, ha ha)
Realistic - XM8 (best I felt)
Hard - VSS Vintorez
Should have 1 weapon for unrealistic as it is the most difficult.
Should be an Esc key to unselect a soldier or command or reselect another soldier with the number keys.
Missions that post a problem:
Stealth missions that heavily out-numbered you, usually have problems.
Patience, wait for them 2 squares from doors together. Take them out 1-by-1 when they come out. Close up on them near narrow alleys & wait. PATIENCE (F-wait all sometimes is your good friend). Bayonet, runner & flash is the best.
Best combo:
If more than 1, listed in descending order fr. best to worst.
Main gun - XM8, M60E4, C9A1 , HK416
Attachment - Bayonet
Item - Flash, Bang
Bonus Stat - Runner
Ability - Bullet Time, Cover
Tips:
1. Work as a team
2. Remember to aim (even knifing/bayoneting & throwing Flash/Stun)
3. Hide 2 squares away from door near walls. 1 square can get hit or stunned/flashed.
4. Flash/Bang then close in
5. Aid is useless as it will be killed instantly if too near. Need to clear the area.
6. Remember to UPGRADE when available. I played mission 1-23 using basic AK-47, grenade & basic abilities. Pretty frustrating.
Bugs:
1. Hangs when enemy re-spawn is slower than bayoneting/knifing/killing them.
2. Enemy re-spawn on a body that is unattackable.
3. Rare unattackability proned on top of a table/box/window sill.
